Synthesis of symmetrically trisubstituted benzene derivatives

Abstract
Syntheses are described of 1,3,5-trisubstituted benzenes with the following substituents CH2Cl, CH2OEt, CH2OBz, and [CH2]2X (X = OH, OAc, OCBz, Cl, Br, CN, or CO2H), an improved route to 1,3,5-tris(hydroxymethyl)-benzene and alternative routes to the corresponding tri-aldehyde and tris(bromomethyl) derivative.
