246. Monofunctional (Dimethylamino)silane as Silylating Agent

The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied.These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine.The resulting products are thermally stable and relatively volatile.Reaction with surface-hydrated silicon-dioxide preparations at a50-250 deg C for 170 h yields a dense grafted layer.However, with (dimethylamino)silanes having strongly polar substituents, a retreatment of the surface-modified silica seems to be necessary in order to attain maximum coverage.

REACTIONS OF CHLORINE MONOFLUORIDE. SUBSTITUTION OF CHLORINE ATOMS BY FLUORINE IN CHLORINE-SUBSTITUTED ALKANES AND ESTERS

In anhydrous hydrogen fluoride under mild conditions chlorine monofluoride selectively substitutes the chlorine atoms in chlorine-substituted alkanes and esters by fluorine with the formation of high yields of the corresponding fluorides.The presence of an alkoxycarbonyl group or difluoromethylene group at the α position to the CHCl group deactivates the chlorine atom, and substitution by fluorine does not occur.In chloroalkanes, from which elimination of the chloride ion leads to sufficiently stable carbocations, substitution by fluorine can be realized in the absence of hydrogen fluoride at temperatures between -20 and -60 deg C.The fluorinating capacity of chlorine monofluoride is increased in the presence of catalytic amounts (3-5percent) of antimony pentachloride.Here the reaction is less selective than in hydrogen fluoride.In certain cases substitution is accompanied by hydride transfers.
