“…Benzo[b]thiophene and dibenzothiophene under thermal conditions, with catalysis by Cu(acac) 2, gave predominantly ylidic derivatives of sulfur. 68 Reaction of 52 with secondary amines is very complex; it follows a sequence of several stages, not fully delineated, as judged by the isolation of two different kinds of enamines, 63 69 and 64, 70 from diethylamine and pyrrolidine, respectively.…”
