Geometrical isomers of 2-hydroxy-2-thio-4-methyl-1,3,2-dioxaphosphorinan (I) and 2- hydroxy-2-seleno-4-methyl-1,3,2-dioxaphosphorinan (V) have been prepared stereospecifically by : (a) demethylation of cis- and trans-2-methoxy-2-thio-4-methyl-1,3,2-dioxaphosphorinan (IV) and 2-methoxy- 2-seleno-4-methyl-1,3,2-dioxaphosphorinan (VI) with trimethylamine, and (b) addition of sulphur and selenium to geometrical

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.
