摘要： Mercaptophenols are selectively oxyalkylated at the mercapto function by a two-step process comprising reacting the mercaptophenol with a silylating agent to form novel silylated mercaptophenol derivatives and thereafter oxyalkylating the phenolic mercapto function to the degree of oxyalkylation desired. Simple hydrolyzing of the resulting product breaks the silylation block forming a hydrolyzed oxyalkylated mercaptophenol.
