Abstract The platinum(0) complex [Pt(PPh 3 ) 4 ] reacts with brominated propargylic amides and esters in benzene by oxidative addition to give trans -[Br(PPh 3 ) 2 Pt–C C–C( O)R] complexes whereas no reaction occurs when halogenated solvents (CH 2 Cl 2 , CHCl 3 ) are used. The cis -ligands PPh 3 can be replaced by P( i Pr) 3 and the bromide by trifluoroacetate. O -Alkylation of those trans -[X(PR′ 3 ) 2 Pt–C C–C( O)R] complexes (X = Br, CF 3 COO; R′ = Ph, i Pr) derived from propargylic amides… CONTINUE READING
