Difluoronitroethyl ethers of 1,2-alkylene glycols and their derivatives

A method was developed for the preparation of the 2,2-difluoro-2-nitroethyl ethers of 1,2-alkylene glycols by reacting 2,2-difluoro-2-nitroethanol with the appropriate olefin α-oxides.

Preparation of 2,2 -difluoro-2-nitroethoxysilanes

A method was developed for the preparation of difluoronitroethoxymethylsilanes of general formula (O2NCF2CH2O)nSi(CH3)4−n by reacting difluoronitroethanol with the appropriate methylchlorosilanes, and some of their properties were studied.

Synthesis and some properties of difluoronitroalkyl acrylates and difluoronitroalkyl methacrylates

1. n nMethods were developed for the preparation of difluoronitroalkyl acrylates and difluoronitroalkyl methacrylates. n n n n n2. n nSome of the conditions for the radical polymerization (using UV irradiation and heat-peroxide initiation) of the obtained compounds were studied, and it was shown that the difluoronitroalkyl acrylates polymerize with the formation of viscous oils, while the corresponding methacrylates polymerize with the formation of solid polymers. n n n n n3. n nSome of the physicochemical characteristics of poly(difluoronitroethyl methacrylate) were determined.

Preparation of vicinal bis(difluoroamino)ketones

1. n nA readily accessible method was developed for the preparation of vicinal bis(difluoroamino)ketones by the reaction of tetrafluorohydrazine with unsaturated ketones. n n n n n2. n nSome of the chemical properties of the synthesized bis(difluoroamino)ketones were studied.
