Polymerizable monomeric carbamates are disclosed. Polymers comprising recurring units from such carbamates undergo β-elimination in an alkaline environment and are useful in diffusion control layers in diffusion transfer photographic products.

journey from the failure of our attempts in controlled oxidation of sulfides to sulfoxides using an Oxone®–KBr combination to our success in the development of a catalyst-free protocol for the oxidation of sulfides to sulfoxides using Oxone as an oxidant. We also describe the failure of our attempts at the oxidation of sulfides to sulfonesusing an excess of Oxone–KBr as well as Oxone, and our success
