摘要

Procedure for obtaining plant growth regulating compositions, characterized in that in a first stage the phospholtanic salts of the formula are prepared: **(See formula)** where R1 signifies alkyl, alkenyl, alkynyl, cycloalkyl, optionally substituted, or aralkyl, optionally substituted in the aryl part, R2 means alkyl, alkenyl, alkynyl, cycloalkyl, optionally substituted or optionally substituted in the part aryl, R3 represents halogen or alkyl, n represents integers from 0 to 2 and A represents an equivalent of an anion of a non-phytotoxic acid; reacting a phospholane of formula: **(See formula)** where R1, R3 and n have the meaning indicated above, with a compound of formula R4-X (III) where R4 signifies alkyl, optionally substituted, alkenyl, alkynyl, cycloalkyl, arylalkyl, optionally substituted in the aryl part or the triethyloxonium ion and X means halogen, alkyl sulfate or tebrafluorborate, optionally in the presence of a solvent at temperatures between 0ºC and 130ºC and, optionally, the anion is then exchanged, or by reacting a phospholtanic salt obtained according to the reaction of above formula: **(See formula)** where R1, R3 and n have the indicated meanings, R5 signifies an alkyl group substituted by a hydroxy group and Y ⊖ means a halide, alkyl sulfate or tetrafluorborate, optionally in the presence of a solvent as well as optionally a catalyst, with a halogenizing agent at temperatures between 0 and 130ºC or by reacting a phospholtanic salt of the formula: **(See formula)** where R1, R2 and Y 8 have the meanings above, optionally in the presence of a solvent with a halogenating agent at temperatures between 0 and 130ºC and the obtained phospholtanic salts of formula (I) are then combined in a second stage with a bulking agent and/or surfactant.
