Notes:
Addition of Silylenes to Iminoboranes[1]Photolytically generated silylenes SiMe2 and SiMes2 are treated with iminoboranes XB≡NtBu [X = tBu, Me3Si(tBu)N, iPr2N: 1a-c]. The products from SiMe2 and 1a are the four-and six-membered rings [-B(tBu)=N(tBu)-SiMe2-SiMe2-] (3a) and [-B(tBu)=N(tBu)—B(tBu)N(tBu)-SiMe2-SiMe2-] (4a), depending on the conditions of the photolysis. SiMe2 reacts with 1b to give the six-membered ring [-BX=N(tBu)-SiMe2-BX=N(tBu)-SiMe2-] (4b). From SiMes2 and 1a,c the three-membered rings [-BX=N(tBu)-SiMes2-] are formed (2a: space group Pbca; 2c: space group P1): SiMes2 reacts with 1b to yield the unexpected four-membered BNSiN ring [B(Mes)N(tBu)-Si(Mes)(SiMe3)-N(tBu)] (5: space group P1).
