The multiply bonded derivatives of the heavier main group elements are among the most challenging targets for synthetic pursuits. Those of them featuring a double bond between the silicon and group 15 element are represented mostly by the silaimines-N-Si and phosphasilenes-P-Si with a very few examples of arsasilenes-As-Si. In this contribution, we report on the synthesis and structural elucidation of the first stable stibasilene and novel phosphasilene and arsasilene derivatives, featuring an identical substitution pattern. A systematic comparison within the series phosphasilene-arsasilene- stibasilene is made on the basis of their experimental and computational studies.

Mono-, bis- and tris(chlorophosphaalkenyl)stibanes have been obtained from Mes*P{double bond, long}C(SiMe3)Li (Mes* = 2,4,6-tri-tert-butylphenyl) or from the phosphaalkene carbenoid Mes*P{double bond, long}C(X)L

Dechlorofluorination of ArSb(F)-C(Cl)CR2 (CR2 = fluorenylidene, Ar = 2,4,6-tri-tert-butylphenyl) by tert-butyllithium afforded a 3,4-bis(fluorenylidene)-1,2-distibacyclobutane. The formation of the latter probably involves the transient stibaallene ArSbCCR2 followed by a head-to-head dimerization via two SbC double bonds. Molecular orbital calculations at the ab initio and DFT levels support the head-to-head dimerization of ArSbCCR2 with the formation of a 1,2- distibacyclobutane.
