The invention relates to derivatives of (1-cyanocyclopropyl)phenylphosphinic acid of the formula (I)
and to salts thereof, of the formula (II),
for enhancing stress tolerance in plants to abiotic stress, preferably to drought stress, especially for enhancing plant growth and/or for increasing plant yield.

1-Phosphoryl-substituted cyclopropanes, cyclobutanes, and cyclopentanes were obtained by the reaction of phosphoryl-substituted esters and nitriles of acetic acid with alpha,omega-dihaloalkanes. The influence of the CH-acidity of the starting compounds and electrophilicity of the alkylating agent on the reaction rate was examined.

The 1-thiophosphorylated esters and nitriles of cycloalkanecarboxylic acids were obtained both by the direct reaction of derivatives of thiophosphorylacetic acids with alpha,omega-dihalogenoalkanes in the K2CO3/DMSO heterophasic system, and as a result of the reaction of the corresponding oxygen compounds with the Louson reagent.
