Abstract

Strong interactions with the lone pairs of the neighboring, pyramidalized phosphorus atoms stabilize the cyclic carbenium ion 2. The 1,3-bis(phosphanyl) carbenium unit was obtained by protonation of a 1,3-diphosphacyclobutane-2,4- dlyl 1 (R = 2,4,6-tBU3C6H2, HX = trifluoromethanesulfonic acid).
