Other Experimental
Organo-functional silanes are noted for their ability to bond organic polymer systems to inorganic substrates. /Silane cmpd/;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/;Hydroxyl radical reaction rate constant = 1.50X10-13 cu cm/molec sec at 25 °C (est)
