摘要
Unusual formation of an eta (2)-bonded polycyanocarbon ligand from tetracyanoethene, C-2(CN)(4) (tcne) and the allylic ligand in Ru{eta (3)-CHPhCHC=CPh(C drop CPh)}(PPh3)Cp* (1), and migration of CN from the polycyanocarbon in Ru{C[=C(CN)(2)]CPh= C(CN)(2)}(dppm)Cp-. (3), have been established by crystal structure determinations on Ru{C(CH=CHPh)=CPhC[CPh= C(CN)(2)]C(CN)(eta (2)-CN)}(PPh3)Cp-. (2) and Ru(CN){C(CN)C[CPh=C(CN)(2)]PPh2CH2PPh2}Cp-. (4), which are the respective products. (C) 2001 Elsevier Science B.V. All rights reserved.
