The phosphorylation ofN-trimethylsilyllactams by phosphorus(III) acid chlorides results in correspondingN-phosphinolactams in high yields. The derivatives thus obtained have been used in the synthesis ofN-phosphoryl- andN-thiophosphoryllactams. The reversibility of the reaction of phosphinolactams has been established.

Butane-2,3-diol and 2,3-dimethylbutane-2,3-diol have been converted into substituted 2-mercapto-2-thiono-1,3,2-dioxaphospholans, and thence into 2-(N-substituted carbamoylmethyl)thio-derivatives. Some new ring-substituted 1,3,2-dioxaphospholans, with alkoxy, alkylthio, and dimethylamino groups attached to phosphorus, have also been prepared from aliphatic 1,2-diols. The hydrolytic stability and insecticidal

A general synthetic procedure leading to cyclic hydrogen phosphites has been devised. The effect of solvent on the P==O and P—H infrared stretching modes of cyclic hydrogen phosphites and thiophosphites has been studied. It is concluded that association of cyclic hydrogen phosphites is attributable to dipole–dipole interactions rather than to hydrogen bonding.
New N-substituted thio (or sulfinyl) aliphatic acylcephalosporin C and their derivatives at the 3rd position have been prepared. The compounds are useful as intermediates for recovering cephalosporin C and deacetoxycephalosporin C from their fermentation broth and also for preparing 7-aminocephalosporanic acid and its derivatives at the 3rd position.
