[Figure not available: see fulltext.] Original method has been developed for the preparation of previously unknown cyclic organosilicon esters of salicylic acid, containing halogen-silicon bonds. This method is based on the reaction of trimethylsilyl ester of 2-(trimethylsiloxy)benzoic acid with organylhalosilanes RR¹SiXY under mild conditions, where R, R¹ = Cl, Me, CH=CH₂, Ph; X, Y = Cl, F.
