High yields of bis-(dialkoxyphosphonyl-methyl)- phosphinic esters, (RO)2 (O)-PCH2P(O)OR, bis-(aloxyphosphinyl-methyl)-phosphinic esters, [R(RO)(O)PCH2]2P(O)OR, are obtained by heating bis-chloromethyl-phosphinic esters, (CICH2)2P(O)OR, with alkylphoshites, phosphonites and phosphinites, repectively, at 170 to 180°C for several hours. Hydrolysis of these esters in achieved by refluxing with conc. HCl

Reaction of derivatives of 1-methyl-2,2-dichlorocyclopropanecarboxylic acid with three- and four-coordinate phosphorus acids was studied. It was established that the nucleophilic substitution on the carbonyl carbon atom proceeds without cleavage of the three-membered ring and leads to new types of phosphorus-containing cyclopropanes. The products were found to enhance the germination energy and laboratory germination of cereal, legume, and vegetable seeds.
