Notes:
The hydrostannylation of phosphaalkynes 8 with tin hydrides 1 depends on the stoichiometry employed: Thus, the 1,2-dihydro-1,3-diphosphetes 10 are isolated when an excess of phosphaalkyne 8 is used. On the other hand, an increase in the tin hydride concentration favors the formation of the phosphanes 11 and 12. Synthesis of the 1,2-dihydro-1,3-diphosphetes 14 and 16 was achieved by the use of diorganotin hydrides 13 or chloro(organo)tin hydrides 4, respectively. An isolated and characterized by-product of the latter reaction was the phosphorus-carbon-tin cage 17. Furthermore, the following reactions of the 1,2-dihydro-1,3-diphosphetes 10 were performed: isomerization reactions, complexation reactions with transition-metal complexes, and substitution of the hydrogen atom by iodine.
