Photolysis of I-(1-alkoxy-l-alkenyl)benzotriazoles gives moderate yields of 2-alkoxyindolenines, which can be hydrolysed to oxindoles. A side reaction leads to the formation of iminooxetanes. The formation of the 2-alkoxy-indolenines is quite insensitive to steric hindrance at the reacting centres.

## Abstract 1‐(Trimethylsilylmethyl)benzotriazole is readily prepared from benzotriazole and chloromethyltrimethylsilane. It undergoes fluoride‐catalyzed desilylation with carbonyl compounds and forms an anion that can be alkylated and acylated readily and undergoes Peterson olefination. 1‐(Cyclohe
