Lincrusta-Walton 1877 -1887: The Development, Design and Character of Lincrusta-Walton
No full textThis thesis contributes towards the understanding of nineteenth-century decorative wall-coverings by establishing a foundational understanding of the first ten years of Lincrusta-Walton, invented in 1877 by Frederick Walton (1834 –1928), the inventor of Linoleum. As a business history, this study builds upon the very limited literary, archival andmaterial reference held by LINCRUSTA® by establishing and highlighting contemporary use. Additionally, an understanding of the foundation of the company will be established by scrutinising previously unexplored primarysources from contemporary trade literature and other published materials sourced through LINCRUSTA®, Crown Paints and other relevant archives and on-line resources. Moreover, this thesis recognises and identifies the earliest dated catalogue within the public domain and establishes the first Lincrusta-Walton designs; whilst also reconciling and illuminating previously unattributed designs by Dr Christopher Dresser and contributions made to the design catalogue by Lewis Foreman Day. Additionally, discussion of the commercial, cultural and consumer history of the company will provide rigor and a contextual rationale from which Lincrusta-Walton and its significance within the home and market setting of the 1870’s and 1880’s, can be more fully appreciated and understood.</p

The oxime portmanteau motif : released heteroradicals undergo incisive EPR interrogation and deliver diverse heterocycles
No full textOA funded through the RCUK OA block grant.Selective syntheses are now available for compounds of many classes, based on C-centered radicals, exploiting a diverse range of mechanisms. The prospect for chemistry based around N- and O-centered radicals is probably more favorable because of the importance of heterocycles as biologically active materials. Heteroradical chemistry is still comparatively underdeveloped due to the need for safe and easy ways of generating them. Oxime esters appeared promising candidates to meet this need because literature reports and our EPR spectroscopic examinations showed they readily dissociated on photolysis with production of a pair of N- and O-centered radicals. It soon became apparent that a whole suite of benign oxime-containing molecules could be pressed into service. The bimodality of the oxime motif meant that by suitable choice of functionality the reactions could be directed to yield selectively products from either the N-centered radicals or from the O-centered radicals. We found that on one hand photolyses of acetophenone oxime esters of carboxylic acids yielded alicyclics. On the other hand, aromatic and heteroaromatic acyl oximes (as well as dioxime oxalates) afforded good yields of phenanthridines and related heterocycles. Easily prepared oxime oxalate amides released carbamoyl radicals, and pleasingly, β-lactams were thereby obtained. Oxime carbonates and oxime carbamates, available via our novel 1,1'-carbonyldiimidazole (CDI)-based preparations, were accessible alternatives for iminyl radicals and hence for phenanthridine preparations. In their second modes, these compounds proved their value as precursors for exotic alkoxycarbonyloxyl and carbamoyloxyl radicals. Microwave-assistance was shown to be a particularly convenient procedure with O-phenyl oxime ethers. The iminyl radicals generated from such precursors with alkene, alkyne, and aromatic acceptor substituents furnished pyrrole, quinoline, phenanthridine, benzonaphthiridine, indolopyridine, and other systems. Microwave irradiations with 2-(aminoaryl)alkanone O-phenyl oximes enabled either dihydroquinazolines or quinazolines to be obtained in very good yields. The fine quality of the EPR spectra, acquired during photolyses of all the O-carbonyl oxime types, marked this as an important complement to existing ways of obtaining such spectra in solution. Quantifications enabled SARs to be obtained for key reaction types of N- and O-centered radicals, thus putting mechanistic chemistry in this area on a much firmer footing. Surprises included the inverse gem-dimethyl effect in 5-exo-cyclizations of iminyls and the interplay of spiro- with ortho-cyclization onto aromatics. Insights into unusual 4-exo-cyclizations of carbamoyl radicals showed the process to be more viable than pent-4-enyl 4-exo-ring closure. Another surprise was the magnitude of the difference in CO2 loss rate from alkoxycarbonyloxyl radicals as compared with acyloxyl radicals. Their rapid 5-exo-cyclization was charted, as was their preferred spiro-cyclization onto aromatics. The first evidence that N-monosubstituted carbamoyloxyls had finite lifetimes was also forthcoming. It is evident that oxime derivatives have excellent credentials as reagents for radical generation and that there is ample room to extend their applications to additional radical types and for further heterocycle syntheses. There is also clear scope for the development of preparative procedures based around the alkoxyl and aminyl radicals that emerge downstream from oxime carbonate and oxime carbamate dissociations.Peer reviewe
Matt Christopher Papers - Accession 1309
No full textThe collection includes letters written by the children’s book author, Matt Christopher, to his son, Marty Christopher. Many of the letters also contain newspaper articles of interest to Matt Christopher, which deal with local sports teams, his writing career, his participation in an exhibition baseball game against the New York Giants in 1938, and other of general interest. Most of the letters are personal in nature, however, a majority of the letters delve into Matt Christopher’s writing career, personal interests, the author’s health, as well as his family life.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/2649/thumbnail.jp
