摘要

Abstract Reaction of 1, 2-bis (diorganophosphino) ethanenickel dibromide (I) with 1, 2, 3, 4- tetraphenyl-1, 4-dilithiumbutadiene (II) at− 30 C yields diphosphannickelacyclopentadiene (III) which at elevated temperatures isomerizes to diphosphanecyclobutadienenickel (0)(IV). The thermodynamic and kinetic parameters of the rearrangement were determined. The structural and conformational analyses of III were carried out by means of 13 C NMR, 31 P ...
