wavelength than 300 nm, undergo photolysis to afford pairs of an organosilylradical and a bis(diisopropylamino)boryl radical by homolytic scission of the silicon-boron bonds. Generation of organosilylradical and organoboryl radical was confirmed by trapping experiments using TEMPO (2,2,6,6-tetramethylpiperidine N-oxyl). The organosilylradical thus generated induces not only silylation of mono-olefins

[Bis(diisopropylamino)boryl](organosilyl)(N-arylimino)methanes, which was formed in the reaction of aryl isocyanides with (organosilyl)bis(diisopropylamino)borane at room temperature, underwent new skeletal rearrangement reaction to provide aryl(1,2-azaboretidin-3-yl)(organosilyl)amines at 110 °C. Reaction of 1,2-diisocyanobenzene with the silylborane afforded 2-(organosilyl)-3-(1,2-azaboretidin-3-yl)-4
