“…[16,17,21,37,[80][81][82] The role played by reaction solvents is important in progressively solubilising solid PCl 5 as the reaction evolves. For example, CCl 4 , in which PCl 5 is soluble, is the most convenient and more frequently used solvent (Scheme 15); [9,10,12,[17][18][19][24][25][26]28,29,31,37,41,[83][84][85][86] benzene and toluene are…”

This review deals with the phosphonate-phosphonochloridate conversion. The different phosphorus-chlorine bond forming reagents (COCl 2 , (COCl) 2 , SOCl 2 , PCl 5 , POCl 3 , Ph 3 PCl 2 , trichloro(o-phenylenedioxy)phosphorane) and the reaction conditions which they impose are considered. Phosphonates / Phosphonochloridates / Chlorinating Agents Version française abrégée -Conversion des dialkyl alkylphosphonates en alkyl chloroalkylphosphonates. La transformation des alkylphosphonates en chloroalkylphosphonates est une réaction très utile en chimie du phosphore. Les chloroalkylphosphonates sont de précieux intermédiaires dans la préparation de dérivés phosphorés plus élaborés tels que, fluoroalkylphosphonates, diesters mixtes, phosphoramideester, thiophosphonates et phosphinates. Plusieurs agents de chloration ont été introduits pour réaliser cette transformation: le phosgène, COCl 2 , le chlorure d'oxalyle, (COCl) 2 , le chlorure de thionyle, SOCl 2 , le pentachlorure de phosphore, PCl 5 , l'oxychlorure de phosphore, POCl 3 , Ph 3 PCl 2 et le trichloro(ο-phenylenedioxy)phosphorane. Les avantages et inconvénients de chaque réactif sont examinés en fonction des critères suivants: disponibilité, efficacité, tolérance, conditions d'emploi, solvant, température, nature des sous-produits. Trois réactifs se détachent, le chlorure d'oxalyle, le pentachlorure et l'oxychlorure de phosphore. Ils réalisent la transformation alkylphosphonates-chloroalkylphosphonates avec efficacité dans des conditions non destructrices et avec des phosphonates d'une grande variété structurale.
