GRAPHICAL ABSTRACT

ABSTRACT

It is shown that increase of steric bulk of R group of 1R-1,2-diphospholes results in decrease of the pyramidality of P(III) atom, but has little impact on a planarity of the entire heterocycle in the case of R = Alk. At the same time, planarization of the heterocycle reported elsewhere for R = SnMe3 or SiMe3 is accompanied by moderate increase of the P(III) pyramidality relative to the case of R = Alk. This difference could be related to effects of π-σ conjugation between P-Sn/P-Si moiety and the dienic system of the 1,2-diphosphole.
