摘要

Abstract Details of the directed ortho metalation of tert-butyl phenyl sulfoxide (1 and 2-and 4- tert-butyl pyridyl sulfoxides (3a, b are described along with comparisons with established metalation directors (CONR 2, OCONR 2, OMOM, SO 2 t-Bu) via inter-and intramolecular competition experiments.
