Characterization of novel sulfonium photoacid generators and their microwave-assisted synthesis.

Ciceron O Yanez¹, Carolina D Andrade, Kevin D Belfield.

Abstract

Microwave-assisted synthesis of triarylsulfonium salt photoacid generators (PAGs) afforded reaction times 90 to 420 times faster than conventional thermal conditions, with photoacid quantum yields of new sulfonium PAGs ranging from 0.01 to 0.4.
