1. Additional specific rates of solvolysis have been determined for acetyl chloride and diphenylacetyl chloride.

2. The inventive cosmetic composition for hair removal uses aluminum complexes or zinc complexes of thioglycolic acid, which are soluble in solvents and which serve to cleave the cystine-sulfur bridges, and tertiary amines in the form of solvolysis catalysts.

3. Solvolysis of 1-OTf-1-14C in unbuffered HOAc resulted in about 32% rearrangement of the 14C-label from C-1 to C-2, a value that is almost the same as that observed for the analogous acetolysis of 1-OTs-1-14C.
