title: Reaction of an allylstannylene with adamantyl phosphaalkyne.
abstract: 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.
