N2 - The first dicyclic fused thiadiazaphosphorin derivatives, namely, [1,3,4]thiadiazolo[3,2-c]-1,2,3-trihydro-[1,3,5,2]thiadiazaphosphorins (3 and 4), were synthesized by intermolecular cyclocondensation of [1,3,4]thiadiazole-2-yl-dithiocarbamic acid (1) or -dithioperoxycarbamic acid (2) with tri(dialkylamino)phosphine. 5-methyl[1,3,4]thiadiazolo[3,2-c]-2-dialkylamino-6-thiono-1,2,3-trihydro-[1,3,5, 2]thiadiazaphosphorin (3) was easily oxided into the 5-methyl [1,3,4]thiadiazolo[3,2-c]-2-dialkylamino-6-thiono-2-oxo-1,2,3-trihydro-[1,3,5,2] thiadiazaphosphorin (4) and 5-methyl-[1,3,4]thiadiazolo[3,2-c]-2-dialkylamino-6-thiono-1,2-dioxo-1,2,3- trihydro-[1,3,5,2]thiadiazaphosphorin (5).
