Abstract
The reaction of [dppmPtCl2] (dppm = bis(diphenylphosphino)methane) with bis(alkynyl)-dimethylstannanes leads to monomeric complexes [dppmPt(C≡C−R)2], 2 (R = H, CH3, C4H9 t, C6H5) in >90% yield. Rearrangement of 2 into the dimeric complexes 3, trans,trans- [Pt2(C≡C−R)4(dppm)2] is catalyzed by traces of various phosphanes. All products are characterized by 1H, 13C, 31P and 195Pt NMR spectroscopy.Keywords
