Abstract
By reacting RC ≡ CMgBr (R = CH3, C2H5, (CH3)Si) with perthiophosphonic anhydrides (R′PS2)2 (R′ = CH3, 4-CH3O-C6H4) alkynyl substituted dithiophosphinic acids RC ≡ C(R′)P(S)SX (X = H) are obtained, the ammonium salts of which can be converted into the esters (X = CH3) with CH3I. While the acids and their salts form numerous metal chelates (X = M/n), the corresponding esters give platinum(0) alkyne complexes [(PPh3)2Pt(RCEEC(R′)P(S)SCH3)] on reaction with Pt(PPh3)4.Keywords
