Catalytic Thioalkylation of Phenols Based on Mannich‐Type Phenol
摘要:
A thioalkylation of phenols involving reactive phenols, aldehydes, and thiols is described under Mannich-type phenol catalysis to afford thiomethyl phenols in good yields.

Heating of thiols, N,N,N′,N′-tetraethylmethylene diamine, and phenols in DMF affords thiomethyl-substituted phenols in high yields. The developed procedure performed well for aliphatic, aromatic, and functionalized thiols.
This invention relates to a process for stabilizing and at the same time phase compatibilising plastics or plastic compositions by incorporating polymeric compounds obtainable by reacting a compound selected from the group consisting of the sterically hindered phenols, sterically hindered amines, lactones, sulfides, phosphites, benzotriazoles, benzophenones and 2-(2-hydroxyphenyl)-1,3,5-triazines, which compounds contain at least one reactive group, with a compatibilisator.
