Abstract 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.
