“…* In a second experiment, in the absence of Et 3 N, the disulfane 7 was formed in small amount, and 6 could be isolated by crystallization of the mixture from petroleum ether. This result confirms that 3c, in analogy to earlier published reactions with 3a,b, 10,11 easily undergoes substitution with S-nucleophiles at the S-atom. Under analogous reaction conditions, in the presence of Et 3 N, the colored organic solution of thiocamphor (5) turned colorless after 10 min.…”
