1,3-Di(tert-butyl)-2,4-bis[2,4,6-tri(tert-butyl)phenyl]-1, 3-diphosphacyclobutane-2,4-diyl was formed from [2,4,6-tri(tert-butyl)phenyl] phosphaacetylene and t-BuLi. In addition, the X-ray diffraction analysis was carried out, together with theoretical ca

The synthesis and x-ray structure analysis of a novel type of carbenoids, aryl-P(=E)=C(Cl)Li(thf)3 (E=N-aryl, C(SiMe3)2), as well as the first example of a 1,3-diphosphetane-2,4-diyl, (aryl-PCCl)2, is reported and on the basis of quantum chemical calculations its bonding situation is discussed. Furthermore, selected examples for the varying reaction behavior of both types of compounds are presented.
