O-benzylation of polyphenolics. Preparation of 1,2,4-tribenzyloxybenzene
Anthoni,Christophersen,Nielsen
, p. 2223 - 2229 (2007/10/03)
The main phenolic by-products in the O-benzylation of 1,2,4-trihydroxy- or 1,2,4-triacetoxybenzene to 1,2,4-tribenzyloxybenzene have been identified as due to incomplete O-benzylation and C-benzylation. In addition, dibenzyldimethyl-ammonium chloride is f
