No full textGhadwal R, Schürmann CJ, Engelhardt F, Steinmetzger C. Unprecedented Borylene Insertion into a C-N Bond. European Journal of Inorganic Chemistry. 2014;2014(29):4921-4926.Carbenes are well established reactive intermediates and play an important role in organic synthesis, whereas the scope of borylenes is rather limited. Selective borylene insertion into a C–N bond to yield boryl‐functionalized N‐heterocyclic olefins (NHOs), [{N(Dipp)N(DippBH)CHCH}CCH2]2 (6) and [{N(Dipp)N(DippBPh)CHCH}CCH2][{N(Dipp)N(2‐iPr‐6‐CHMeCH2BC6H3)CHCH}CCH2] (8) (Dipp = 2,6‐iPr2C6H3) is reported for the first time. KC8 reduction of (IPrCH2)BRX2 adducts (IPrCH2 = {N(Dipp)CH}2CCH2; R = X = I (2); R = Ph, X = Cl (4)) affords compounds 6 and 8. Surprisingly, treatment of (IPrCH2)BHCl2 (3) with KC8 yields completely unexpected diborane compound (IPr)BH2BH2(IPr) (7). Compound 2 is unstable in THF and induces ring opening reaction to form the borenium ion [(IPrCH2)B{O(CH2)4I}2]I (5

1897 - The Franciscans in California, Zephyrin Engelhardt
No full textEngelhardt noted that much had bee written about those who first introduced Christianity and civilization in California but little was reliable due to ignorance, malice, exaggeration and misstatements. Up to 1785, Engelhardt consulted original Spanish documents and compared those with statements of H. H. Bancroft. According to the author, with regard to the missions from 1831 through 1850, Bancroft was almost the only authority offering any accurate information. He believed as to historic facts, that Bancroft\u27s work was reliable and all the more valuable because it came from a non-Catholic source.https://digitalcommons.csumb.edu/hornbeck_spa_2/1006/thumbnail.jp

Libertarian Bioethics and Religion: The Case of H. Tristram Engelhardt, Jr
No full textThis paper is a critique of certain moral perspectives that are found in the second edition of Engelhardt's Foundation of Bioethics. These views are spelled out in explicit detail in his second edition, and follow on the heels of a profound religious conversion. Engelhardt is an eminent bioethicist with strong religious convictions that overlay much of his writing. The author wishes to question some of the conclusions that Engelhardt reaches as they touch upon moral frameworks, pluralism, and a 'secular' bioethics
