COPOLYMERIZATION OF N-ACRYL-N,N′-DICYCLOHEXYLUREA AND N-METHACRYL-N,N′-DICYCLOHEXYLUREA WITH STYRENE

Journal of Macromolecular Science, Part A, 2001
N-Acryl-N, N´-dicyclohexylurea (A-DCU) homopolymers and copolymers with styrene (St) are prepared under the standard free-radical-initiated polymerization. Copolymers of A-DCU with St prepared under different monomer-to-monomer ratios in the feed, have random composition with an azeotropic point at ratio of 0.73 (A-DCU) to 0.27 (St).

It was found, that the interaction of the dialkylamidines and tetraalkylguanidines with sulfur tetrafluoride leads to substitution of the imido group to the fluorine atoms. This reaction takes place in the much more mild condition then such reaction for the carbonyl compounds.

N,N?-dialkyl-N,N?-dinitrosulfodiamides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989
N,N′-dinitrosulfodiamides are formed in the nitration of sulfodiamides with concentrated nitric acid or nitronium borofluoride, and also on substitutional nitration of the corresponding N,N′-di-tert.-butyl derivatives with those reagents. Sulfuryl chloride reacts with the disodium salt of ethylene N,N′-dinitramine to produce 2,5-dinitro-1,2,5 ...

Cyclopalladation of N,N,N?,N?-tetramethylisophthalthioamide

Transition Metal Chemistry, 1995
N,N,N′,N′-Tetramethylisophthalthioamide (Hmpt) was cyclopalladated with PdCl2 in hot dimethylsulphoxide to give [PdCl(mpt)]. The structure was determined by X-ray analysis. The thioamide is metallated at C(2) to act as an S528-01C528-02S tridentate anionic ligand.

Succinimidation by N-bromosuccinimide of N,N-dimethylamido and N,N-dimethylamino groups

Journal of the Chemical Society, Perkin Transactions 1, 1984
N,N-Dimethylamides (1)–(6) and N,N-dimethylamines (7)–(10) are converted by the action of N-bromosuccinimide (NBS) in carbon tetrachloride and in the presence of a catalytic amount of benzoyl peroxide into the corresponding succinimido derivatives (11)–(23).
