BIS(TRIPHENYLPHOSPHINE)PLATINUM ACETYLIDES FROM FUNCTIONALLY SUBSTITUTED ACETYLENES - NEW SYNTHESIS METHOD

A 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.
