When performed in the presence of cyanide and at pH smaller than 5, the RuO4-mediated oxidation of secondary amines Bn-NH-R (1a-b; R=Me, Et) gave mainly 1-cyanoformamidines Bn-NR-C(=NH)-CN (2a-b) and their hydrolysis products Bn-NR-COCN (3a-b), Bn-NR-CN (4a-b), Bn-NR-CONH2 (5a-b). Carboxamides 5a-b can result also directly from 1a-b. (Chemical Equation Presented).
Synthesis of imidazolidin-2-ones employing dialkyl carbonates as an ecofriendly carbonylation source
Badru, Rahul,Singh, Baldev
, p. 38978 - 38985 (2014/11/07)
A new approach to the synthesis of imidazolidin-2-ones by carbonylation of vicinal diamines with dialkyl carbonates using Pb(NO3)2 and Cu(ii) salts as catalysts has been described in the present protocol. A comparative study using Cu(ii) salts and Pb(NO3)2 as catalysts has suggested Cu(NO3)2 and CuCl 2·2H2O salts to be as promising as Pb(NO 3)2 and can replace the latter in the carbonylation reactions employing dialkyl carbonates. the Partner Organisations 2014.
