Abstract

Abstract The synthesis of N, N′-alkyl 1, 2-phenylenediamines 1, 2-C 6 H 4 (NHR) 2 [R= CH 2 CH 2 CH 3 (nPr), CH 2 tBu (Np)] was carried out in three steps by lithiation of the primary 1, 2-phenylenediamine, reaction with the appropriate acyl chloride and reduction with LiAlH 4. The addition of nBuLi to a stirred solution of N, N′-alkyl diamines in cold hexane resulted in the immediate deposition of the corresponding lithium salts, which react with [MCp R′ ...
