SYNTHESIS AND STRUCTURE OF METHYL-SUBSTITUTED 1,3-DIOXA-2-SILACYCLOHEXANES

The reaction of dimethyl(diethylthio)silane with 1,3-diols gave methyl-substituted 1,3-dioxa-2-silacyclohexanes. 1H and 13C NMR spectroscopy were used to study the configuration and predominant conformations of the compounds studied.

Flame retardant dimethyl silicic acid neopentyl glycol ester compound and its preparation method

The invention relates to a dimethyl silicon acid neopentyl glycol ester compound serving as a fire retardant, and a preparation method of the dimethyl dibromoneopentyl dioxygen base ring silanization compound. The structure of the compound is shown in the following formula in the specification. The preparation method comprises the following steps: in a temperature range of 70-130 DEG C, performing a reaction on dimethyl dichlorosilane or dimethyl dibrom silicon alkane with neopentyl glycol, with the molar ratio of 1:1 for 4-8 hours, and performing purification so as to obtain the dimethyl silicon acid neopentyl glycol ester. The dimethyl silicon acid neopentyl glycol ester disclosed by the invention is high in flame resistant efficacy, has the functions of carbon forming and dripping prevention, and is suitable for being used as the fire retardant of polyvinyl chloride, polyurethane, an epoxy resin, an unsaturated resin and the like. The production technology is simple, the investment of equipment is few, the cost is low, and the industrialized production is easy to realize.

Clean nitrations: Novel syntheses of nitramines and nitrate esters by nitrodesilylation reactions using dinitrogen pentoxide (N2O5)

In this novel nitration method dinitrogen pentoxide (N2O5) in an inert solvent is used as the nitrating agent, thereby removing the need for strong acids as the reaction medium. The N2O5 cleaves heteroatom-silicon bonds, in silylamines and silyl ethers respectively, to yield the desired energetic groupings (nitramines or nitrate esters respectively) without liberation of acids which would occur with conventional substrates (amines or alcohols). These nitrodesilylation reactions proceed cleanly and in good yield, and the scope of the reaction is illustrated by 29 examples, some of which produce high energy compounds, notably plasticisers and an energetic polymer precursor. These reactions are therefore potentially clean nitrations for the manufacture of energetic compounds which will minimise the impact of this activity on the environment in the future.
