| Abstract: | The treatment of tert-alkyl phenyl thioketones with Lawesson’s reagent (LR) gave two diastereomeric 1,3,2-dithiaphosphetane 2-sulfides in high yields. The structure of one of the major diastereomers was determined by X-ray crystallography. The reaction of 2-adamantanethione with LR yielded the corresponding spiro-1,3,2-dithiaphosphetane 2-sulfide derivative in 87% yield. |
