Özet
Alkoxy- and thiocarbene complexes of chromium and tungsten afford different type of products on reaction with (N-aryl)imidoyl chlorides. The (n-butyl)ethoxycarbene complex [(OC)5W=C(OEt)n-Bu] and (N-aryl)imidoyl chlorides t-BuClC=NC6H4R4 (R4 = H, OMe) undergo a rearrangement to (N-enamino)ethoxycarbene complexes, whereas quinolines are obtained from the corresponding reaction of(alkyl)thiocarbene complexes [(OC)5M=C(SEt)CH2R] (M = W, Cr; R = n-Pr,Me)with (N-aryl)imidoyl chlorides R1ClC=NC 6H2R2R3R4 (R1 = t-Bu, Ph; R2, R3 = H, HC=CH-CH=CH; R4 = H, OMe, Me) by β-cyclization. © 2010 American Chemical Society.
