The new phosphinocyclotriphosphane (t-BuP)2P-P(SnMe3)2 (1) has been obtained by reaction of di-tert-butylchlorocyclotriphosphane with tris(trimethylstannyl)phosphane, and has been isolated in pure form. The yellow solid is stable below 0°C under inert conditions. Compound 1 is a dynamic molecule, as the P atom of the [bis(trimethylstannyl)phosphino] group has a very low barrier to inversion due to the bulky and electropositive Me3Sn substituents.
