Storage of Silan- and Germanimines Me2E=NR (E = Si, Ge) by Way of Sila- or Germadihydrotetrazoles

Silan- and germanimines Me2E=NR (1, 2) ntBu3-n, SiPh3, EMe2N(SiMe3)2> react with azidoalkanes or -silanes R'N3 ntBu3-n, SiPh3, SiMe2N(SiMe3)2> by cycloaddition to form sila- or germatetrazoles 5, 6 (in addition, insertion products of Me2E=NR in the R'N bond of the azides and others are formed in some cases).The sila- or germadihydrotetrazoles decompose at raised temperatures in a first-order reaction, reversing their formation by cycloreversion into azides R'N3 or RN3 and imines Me2E=NR or Me2E=NR' (rate constants: Table 1).Consequently, azides operate as stores for silan- and germanimines.The unsaturated systems are formed only as short-lived intermediates.Their stabilization, as a rule, takes place by dimerization and/or insertion of the imines into the RN or R'N bond of the azides, formed as well by thermolysis of dihydrotetrazoles.

Reactivity of the Germaethene Me2Ge=C(SiMe3)2

Germaethene Me2Ge=C(SiMe3)2 (2), generated as a reaction intermediate by thermal elimination of LiX from Me2XGe-CLi(SiMe3)2 or by thermal cycloreversion from the adduct 2*Ph2CO, combines with reactants a-b (e. g.MeO-H) under insertion into the a-b bond (formation of 4), with a=b-c-H (e. g.CH2=CR-CH2-H; R = H, Me, CMe=CH2) under ene reaction (formation of 19 - 21), and with ab 3-nMenSi), O=N=N or CH2=CR-CR=CH2 (R = H, Me)> under , , and cycloaddition (formation of 6, 7 or 9 - 14 or 17, 18).By comparison with the silaethene Me2Si=C(SiMe3)2 (1), 2 is less Lewis acidic and its double bond is less polar.
