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NC6H2R2R3R4 (R1 = t-Bu, Ph; R2, R3 = H, HCCH−CHCH; R4 = H, OMe, Me) by β-cyclization.
