Gaifa Lai, Xiu Ren Bu, J. L. O. Santos, Eric A. Mintz

Abstract

All articles of this category Two previously claimed results on the Vilsmeier-Haack formylation of triphenylamine were demonstrated to be in error and the unambiguous reproducible procedures were developed to prepare 4-formyltriphenylamine ( 3 ) and 4,4'-diformyltriphenylamine ( 4 ), respectively, in good yields. Vilsmeier-Haack formylation - triphenylamine - 4-formyltriphenylamine - 4,4'-diformyltriphenylamine
