of ferrocene and arenes with P4S10. Reaction of these compounds and Lawesson's
reagent with alkenes, 2,3-dimethylbutadiene and other compounds gave organo-sulfur
phosphorus compounds including 1,2-thiaphosphetane-2-sulfides such as P-ferrocenyl
1,2,5,5,7,8-hexamethyltricyclo[3,2,5,2,0]-3-thia-4-phospho-oct-7-ene-4-sulfide and a
thiaphosphorine sulfide (P-ferrocenyl 4,5-dimethyl-3H,6H-1,2-thiaphosphinine-2-sulfide).
Treatment of P-ferrocenyl thiaphosphorine sulfide with BuLi followed by carbon containing
electrophiles (such as benzyl bromide or 2,4-dinitrochlorobenzene) gave ring-opened
products. In addition treatment of dithiadiphosphetane disulfides with organic carbonyl
compounds, including ketones, gave thiocarbonyl compounds. Platinum complexes were
formed from the dithiadiphosphetane disulfides. [Continues.]
