Other Experimental

Combustible;Reacts with water or steam to produce toxic and corrosive fumes;BP: 223 °C at 10 mm Hg;The reaction of organosilanes with halogens and halogen cmpd usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/
