The reaction of a terphenyl tin(ii) compound bearing an η(3) coordinating allyl ligand with adamantyl phosphaalkyne is reported. The quantitative stochiometric reaction towards one product involves an addition of one Sn-Ar bond across the C[triple bond, length as m-dash]P triple bond and formation of a phosphadistannacyclobutene ring. This kinetically favoured product can be isolated in the solid state, however, in solution, it shows rearrangement towards a new tin-phosphorus molecule over a period of five days.
报道了一种带有η(3)配位烯丙基配体的三联苯锡(II)化合物与金刚烷基磷炔的反应。对一种产物的定量化学计量反应涉及一个Sn-Ar键加成到C≡P三键上并形成一个磷二锡环丁烯环。这种动力学上有利的产物可以以固态形式分离出来，然而，在溶液中，它在五天的时间里会重排为一种新的锡-磷分子。
