- Abstract
The thf-complexed silanimine tBu2Si=N–Sit- Bu3·thf (1(thf); monoclinic, space group C2/c) was prepared by the reaction of 1 equivalent of tBu2SiClN3 with 1 equivalent of Na[SitBu3] in Bu2O and subsequent addition of thf. By heating a benzene solution over a period of 11 d –140 °C, 1(thf) slowly released the thf donor to form the uncomplexed silanimine 1. However, under these conditions the silanimine 1 is unstable and is thermolized to give the ene reaction product of 1 with isobutene, H2C=C(CH2SitBu2–NH–SitBu3)2. By contrast, the thermolysis reaction of Me2Si=N–SitBu3·thf yielded the silanimine dimer (Me2SiNSitBu3)2 in 51 % and the vinyl ether Me2Si(OCH=CH2)NHSitBu3 in 49 % yield.
