摘要
The aminocarbene complexes (CO)5Cr=C(R1)N(R2R3) 1 [R1 = H, Me, Ph, R2 = Me, R2R3 = (CH2)5, R3 = Me, cyclopropyl] react with diphenylacetylene to give nitrogen ylides 5 which were fully characterized by an X-ray analysis carried out on 5a [(CO)3CrR2R3N(C16H10OR1)-(R1 = H, R2 = R3 = (CH2)5] and which lead, upon nitrogen to carbon migrations of alkyl groups R2 and R3, to the expected lactams (e.g. 8 and 9) C16H10ONR1R2R3.
