Popis: The reaction of PhC(NtBu)2SiCl (L) with N2O afforded the trimer {PhC(NtBu)2Si(O)Cl}3 (1), which contains a Si3O3 six-membered ring. In the molecular structure of 1, the PhC(NtBu)2 moieties are arranged around the Si3O3 six-membered ring in a paddle-wheel fashion. Further the reaction of L with B(C6F5)3 and 9-BBN (9-borobicyclo[3.3.1]nonane) yielded the chlorosilylene–boron adducts L·B(C6F5)3 (2) and L·9-BBN (3). The reaction of CH{(C=CH2)(CMe)(2,6-iPr2C6H3N)2}Si (L′) with N-benzylideneaniline resulted in 4, a [1+4]- rather than a [1+2]-cycloaddition product. Compounds 1–4 were characterized by elemental analyses and spectroscopic methods. The molecular structures of 1, 2, and 4 were established unequivocally by single-crystal X-ray structural analysis. The formation of products 1 and 4 was supported by DFT calculations.
