标 题:Microwave-assisted formation of sulfonium photoacid generators

摘要:Efficient method for preparing sulfonium photoacid generators (PAGs) by microwave-assisted reaction of diarylsufides in the presence of alkylaryliodonium salts. Microwave-assisted synthesis of the PAGs is significantly faster, reducing reaction time with less energy consumption. Reaction times using the microwave-assisted synthesis are in a range of from 90 to 420 faster than conventional thermal conditions. The photoacid quantum yields of several salts prepared by the microwave reaction were measured; the photoacid quantum yields of new sulfonium PAGs were in a range from 0.01 to 0.4 times greater than yields from conventional synthesis. Incorporating a nitro group in the structures of the sulfonium salts increased photoacid quantum yield, induced intersystem crossing and increased the efficiency of photoacid generation compounds.

摘要:Aromatic sulfides including diarylsulfides and poly(arylene sulfides) are produced in a novel synthesis in high yield under moderate conditions by heating an aromatic disulfide in the presence of aromatic halide, in which the halide is chloride, bromide or iodide; the diaryl sulfides are useful precursors and starting materials for a range of compounds and the poly(arylene sulfides) are important high temperature engineering thermoplastics.

摘要:A method for the preparation of selectively substituted benzene derivatives by application of solid phase synthesis is disclosed. In particular, the invention provides a novel method for the preparation of substituted benzene derivatives containing two or three groups bound to the benzene ring via nitrogen-, oxygen-, sulphur-, selenium- or carbon-carbon bonds, by application of solid phase chemistry alone or in combination with post cleavage solution phase derivatisation.
