Abstract

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.
