Preparation and Reactions of α‐Halogenobenzyl‐silanesα‐Bromobenzyl‐dimethylchlorosilane3, bis‐(α‐bromobenzyl)‐dimethylsilane8and the corresponding α‐chlorobenzyl‐compounds5and13have been prepared by reaction of benzyl‐dimethylchlorosilane1resp. dibenzyl‐dimethylsilane2with N‐bromosuccinimid and sulfurylchlorid.The α‐halogenobenzyl‐dimethylchlorosilanes3and5have been treated with water, alcohols and phenol, to give the corresponding silanols15and16, siloxanes17and18, alkoxy‐ and phenoxysilanes19and20.Reactions of3with brenzcatechin, o‐aminophenol and o‐aminobenzylalcohol give 6‐
