Toward a 1,4-Diphosphinine-Based Molecular CPS-Ternary Compound

Abstract: Synthesis of the tricyclic 1,3-dithiole-2-thione-derived 1,4-dihydro-1,4-diphosphinine is presented using a base-induced ring formation protocol and chloro­(diethylamino)­(1,3-dithiole-2-thion-4-yl)­phosphane as the starting point. P-oxidation reactions of dihydrodiphosphinine by chalcogens led to bis­(P-oxide), bis­(P-sulfide), or bis­(P-selenide), respectively; all tricyclic compounds were obtained as cis/trans mixtures. 1,4-Dihydro-1,4-diphosphinine was converted into 1,4-dichloro-1,4-dihydro-1,4-diphosphin… Show more

“…In the cases of 4d–f , 31 P{ 1 H} NMR monitoring showed a clean conversion into the corresponding isomeric mixtures of desired products with resonance signals (Table 4) comparable with the previously reported chemical shifts from Avarvari 13 and for the 1,3-dithiole-2-thione derived tricyclic compound. 18 But for 4a,b , due to the accessibility of hydrogen atoms at the opposing ring in the TTF unit, reactions with LDA were not selective and the desired 1,4-dihydro-1,4-diphosphinines were obtained just as a minor product ( 4a ) or were not formed at all ( 4b ). The major products which were formed in these reactions were the related mono-bridged compounds ((TTF) 2 PR), also the formation of a precipitate that was not soluble in common solvents could be an indication for oligomeric side-products.…”
