## Abstract A synthesis of Cโchlorinated analogues of 1,5โdiazaโ2,4โdiphosphorinanโ6โones is described. The Pโchlorophosphine 3, a key compound for all reported substitution reactions, reacts in an unusual way with N,NโฒโdimethylโN,Nโฒโbis(trimethylsilyl)urea to give the unsymmetrical product 5, the

The title compound 1 was allowed to react with catechol, 2,3-dihydroxynaphthalene, tetrabromocatechol, resorcinol, saligenin, and 3,5-di-tert-butylcatechol in the presence of triethylamine to form compounds 4a-4d and 4f. Whereas the catechol derivative 4a, the naphthol derivative 4b, and the tetrabr

In connection with other work it became necessary for us to prepare 2,3,6-trichloro-4-โขercaptopyridine (II). A sulphur atom in organosulphur compounds, such as thiophens (1) and benzo[&]thiophens (2), is known to be capable of complexing with n-butyl-lithium, and it seemed, therefore, ihat reaction
