摘要:
The ethylene complex [(Ar"O)2Ti(eta-2-C2H4)-(PMe3)] (Ar"O = 2,6-diphenylphenoxide) reacts with PhCH2N=CHPh to produce the 2-azatitanacyclopentane complex [(Ar"O)2Ti(CH2CH2CHPhNCH2Ph)], which undergoes coupling reactions with alkynes and benzonitrile to produce new azametallacycles with loss of ethylene.
