摘要

Unlike bis (diphenyl) phosphine derivatives in general,(2S, 4S)-pentane-2, 4-diyl-bis (5H- dibenzo [b] phosphindole), S, S-BDBPP, gives a trans oligomeric compound [PtCl2 (S, S- BDBPP)] n, 1, in reaction with dichloro-Pt precursors such as PtCl2 (PhCN) 2, PtCl2 (CH3CN) 2 and PtCl2 (COD) at room temperature. Compound 1, which could be readily isolated, slowly rearranges in solutions at room temperature to the expected cis-monomer ...
