Abstract
Procedure for the preparation of beta-halogenoethylsilanes, active matter in plant growth regulating agents, of the general formula **(See formula)** in which Y means chlorine or a radical -OR3, X stands for chlorine or bromine, R1, R2 and R3 stand for, independently of one another, alkyl radicals, alkyl radicals substituted by halogen, alkoxy, alkynyloxy, phenoxy, cycloalkyl, alkylthio, alkoxycarbonyl, by heterocyclic radicals and/or by di- and tri-alkylammonium radicals of alkenyl, halogenoalkenyl, alkynyl and cycloalkyl, phenyl radicals optionally substituted one or more times by cyano, nitro, alkyl halogenoalkyl, alkoxy, alkylthio, alkanoyl and/or alkoxycarbonyl, benzyl radicals optionally substituted one or more times by alkyl, alkoxy and/or halogen, one or more of the symbols R1, R2, and R3 also mean the group -CO-R4 in which R4 represents an alkyl, alkenyl or alkynyl radical, a halogenoalkyl or halogenoalkynyl radical, an alkyl or alkenyl radical substituted by cycloalkyl or phenyl, wherein the phenyl can be substituted by alkyl, alkoxy and/or halogen, it also represents a radical of alkoxyalkyl, alkoxycarbonylalkyl, benzoylalkyl or a phenyl radical optionally substituted by halogen, lower alkyl or alkoxy and finally a 5- or 6-membered heterocyclic radical, in addition R1 and R2, also in the meaning of -COR4 can form together with the atoms neighbors, a saturated or unsaturated heterocyclic ring system containing Si, characterized in that particularly when X represents bromine, beta-bromoethyltrichlosilane is reacted with at least 2 equivalents, preferably with 3 equivalents of an acid of formula IV R4-CO - OH (IV) and optionally with the anhydride of said carboxylic acid that would have formula V R4-CO - O-CO - R4 (V) to form a compound of the formula **(See formula)** where Y'means chlorine or the radical -OCOR4, and if desired in the form of step one, two or all three existing -O-CO-R4 radicals are exchanged with respect to alcohol radicals of the formulas R1OH, R2OH and/or R3OH, where R1, R2 and R3 are as it has been defined above, excluding the significance -CO-R4.
