REACTIVITY OF ISOPROPENYLACETYLENE, H-C=C-C(CH3)=CH2, IN THE PRESENCE OF THE COMPLEX [NI(NCS) (C=C-C(CH3)CH2)(PPH3)2]
No full textBis(triphenylphosphine)platinum acetylides from functionally substituted acetylenes. A new synthesis method
No full textA general procedure, giving high yields for the synthesis of (Ph3P)2Pt(CCR)2 complexes (R = C6H5, C(CH2)CH3, (CH2)6CCH, CH2OH, CH(OH)CH3, CH(OH)C6H5, CH2CH(OH)CH3, C(OH)(CH3)CH3, C6H10OH, C(OH)(CH3)CH2CH3, CH2NHCH3, CH2NHCH2C6H5, CH2N(CH3)2, CH2N(C2H5)2) is reported. On the basis of the low frequency IR spectra a trans structure is proposed for all complexes. UV spectra are also reported. © 1979

Far infrared spectra of zeovaent platinum-acetylene complexes
No full textThe low frequency IR spectra of a series of (Ph3P)2Pt(HC7z.tbnd;CR) complexes have been measured in the range 600-300 cm-1. PtP and PtC stretching frequencies have been assigned by comparison with spectra of similar platinum complexes. © 1974
