The formation of a novel Lewis acid-base complex between the silyl azide Si(CH3)3N3and GaCl3having the formula (H3C)3SiN3·GaCl3(1) is demonstrated. The X-ray crystal structure of 1 shows that the electron-donating site is the nitrogen atom directly bonded to the organomet...

It also interests in several mechanistic issues: the nature of the Lewis base initiation process, the chain‐carrying species, the active nucleophile, and silicon activation of the carbonyl substrate. The chapter also reviews the general mechanistic mechanism. The central mechanistic questions in the ...
