“…23 Subsequently, nucleophilic attack of another molecule of ethylene towards the LUMO of 10 affords germylene 14 , which is expected to easily undergo a [1+2] cycloaddition reaction between a further molecule of ethylene and the second germylene moiety. While this [1+2] cycloaddition reaction should be reversible, 24 considering the results of the NMR monitoring reactions, the intramolecular C–Ge insertion of 14 is expected to proceed irreversibly to provide the thermodynamically stable product 1,4-digerma-bicyclo[2.2.0]hexane ( 12 ).…”

The first thermally robust Ge(II) -Sn(II) compound 1 and the structurally characterized Sn(II) -Sn(II) analogue 2, which maintain their structural integrity in solution, were obtained by treating MAr2 (M=Ge, Sn; Ar=2,6-(Me2 N)2 C6 H3 ) with Sn[1,8-(NR2 )2 C10 H6 ] (R=CH2 tBu). On the basis of structural and spectroscopic data, the M-Sn bond is regarded as the interaction of a MAr2 donor with an Sn[1,8-(NR2 )2 C10 H6 ] acceptor.

The preparation and photolysis (350 nm) of Si, Si'-di-terf-butyltetramesitylsiladigermirane, 1, has been investigated. The structure of the siladigermirane 1 has been determined by x-ray crystallography: crystals are monoclinic, space group C2/c with Ζ = 4 in a unit cell of dimensions a = 11.5830(9) A, b = 21.268(3) A, c = 17.534(2) A and β = 108.60(1)°. The structure was solved by direct methods and refined by full-matrix least squares on F 2 on the basis of 2361 observed reflections (Ι>2σ(Ι)) to R, and wR 2 values of 0.0495 and 0.0939, respectively. Photolysis of 1 in the presence of methanol gave two major products: MeSjGehKOMe) and i-Bu 2 Si(OMe)GeHMes 2 , 2 in a 1:1 ratio.Similarly, photolysis of 1 in the presence of water led to the isolation of f-Bi^SKOhOGeHMeSz, 3. The formation of compounds 2 and 3 is best explained by the regioselective photochemical cleavage of the siladigermirane to give MeSzGe: and /-Bu 2 Si=GeMes2, 4, followed by trapping of the germasilene, regioseledively, by water and methanol. Attempts to prepare a solution of germasilene 4 by photolysis of siladigermirane 1 in triethylsilane, a selective trapping reagent for MeSjGe:, were unsuccessful. The germasilene 4 undergoes photodissociation to yield another equivalent of Mes^e: and f-Bu 2 Si:, which were subsequently trapped by the silane.Brought to you by | Purdue University Libraries Authenticated Download Date | 5/27/15 7:32 PM
