Jonczyk, Andrzej published the artcileReactions of organic anions; LXXXV. Catalytic two-phase alkylation of cyanamide, Name: N,N-Dibenzylcyanamide, the publication is Synthesis (1978), 882-3, database is CAplus.
R2NCN (R = PhCH2, H2C:CHCH2, Bu, Et, Me2CHCH2CH2, Me2CH, Me, MeOCH2, BuOCH2) were prepare by reaction of H2NCN with RX (X = Cl, Br) in presence of Aliquat 336. The heterocycles I [Q = (CH2)n, n = 2, 3, 4; o-C6H4] were similarly prepared from H2NCN and BrCH2QCH2Br.
