Synthesis of ortho-alkylated 4,4'-diaminodiphenylmethanes
Chiang,Mei
, p. 7869 - 7872 (2007/10/02)
Procedures are described to convert 4,4'-diaminodiphenylmethane into its ortho-(methylthiomethyl) derivatives. Mechanism for formation of ortho-dialkylated products is discussed and generalizations for dialkylation are founded.
