Nucleophilic substitution reactions of benzyl- and diphenylmethylphosphonamidic chlorides with amines: Competition between the usual SN2(P) mechanism and elimination-addition with an alkylideneoxophosphorane (phosphene) intermediate

The substitution reaction of PhCH2P(O)(NMe2)Cl with Me2NH or Et2NH in CHCI3 is very sensitive to the bulk of the nucleophile (≥ 200 times slower with Et2NH), affords only the product derive

Phosphorylation of Adamantane and its Derivatives in Trifluoroacetic Acid Medium

The possibility of dichlorophosphorylation of the carcass compounds of the adamantane series and of aryl(alkyl)carbinols, with phosphorus trichloride in the low-nucleophilicity trifluoroacetic acid medium was first demonstrated. A new preparative method for introducing a POCl2 group into the bridgehead and bridge positions of the adamantane nucleus, as well as into the α position of the side chain was developed. Some intermediate adamantyl cations may undergo isometizations, among them skeleton ones. A mechanism of the phosphorylation was proposed.
