✦ Synopsis

The kinetic3 of [!-atom abstraction from silancs is shown to bc \vell described by th;: HEBO method cscqt for reaction (S): D + SiH4 -SiE-13 + ftD and Its isotopicanalogues.

In photochcm;.-nl csperiments ai -13O'C it is found that reaction (8) crln compc:c \vith (7): D f CrDj -+ C3Ds (k,/ks = 1.7) and must therefore be wry fast. Evidence from flow csperiments ;IS uell as CNDO/:! calculations support the hypothesis tfxt (8) proceeds via Ltn intermediate SiHs rxdiwl.
