While the dithiolene-based N-heterocyclic silane ( 4 ) reacts with two equivalents of BX 3 (X = Br, I) to give zwitterionic Lewis adducts 5 and 8 , respectively, the parallel reaction of 4 with BCl 3 results in 10, a dithiolene-substituted N-heterocyclic silane, via the Si-S bond cleavage. Unlike 5...
