资源简介：
Development of efficient
bond formation reactions remains important
in organic and main-group-element chemistry. Herein, we report the
metal-free one-pot condensation reaction of 1-iodo-3-trimethylsilyl-substituted
bicyclo[1.1.1]pentasilane (BPS) in the presence of 4-(dimethylamino)pyridine
(DMAP) providing oligomers of BPS, persila[n]staffanes
(n = 2, 3), which involves the successive Si–Si
bond formation reaction accompanied by the concomitant formation of
iodotrimethylsilane (TMSI) in the form of a DMAP complex. The computational
study suggests that the formation of a pentasila[1.1.1]propellane–DMAP
complex resulting from the elimination of TMSI from the BPS is a key
intermediate.
