摘要

Abstract The structure of 1, 4-diphenylpiperazine (1) was determined; it crystallized in the orthorhombic space group Pbca, a= 8.6980 (7), b= 8.4287 (7), c= 17.6359 (15), V= 1292.94 (19), Z= 4. Three novel N, N′-disubstituted piperazines were synthesized via reductive amination of piperazine or N-diphenylmethylpiperazine. The products were characterized by NMR and X-ray crystallography. 1, 4-Diphenethylpiperazine (2) crystallized in the ...
