title: Photoinduced Reactions of Tri-tert-butylindium with (Diethylamino)trimethylstannane and (Di-n-butylamino)trimethylstannane.
abstract: The preparations of [(t-Bu)(2)InNEt(2)](2) and [(t-Bu)(2)InN(n-Bu)(2)](2) by the photoinduced reactions of (t-Bu)(3)In with Et(2)NSnMe(3) and (n-Bu)(2)NSnMe(3), respectively, have been investigated. The isolation and characterization of products other than [(t-Bu)(2)InNR(2)](2) in these reactions clearly indicate that the reactions of (t-Bu)(3)In with R(2)NSnMe(3) do not proceed by simple alkyltrimethyltin elimination. A possible radical mechanism for the formation of the byproducts has been suggested. X-ray crystallographic studies indicate that both compounds are dimeric in the solid state. Crystallographic data: for [(t-Bu)(2)InNEt(2)](2), orthorhombic space group Pbca (No. 61), a = 19.135(7) Å, b = 19.670(6) Å, c = 15.793(7) Å, V = 5944.41(5) Å(3), rho(calcd) = 1.346 g cm(-)(3); for [(t-Bu)(2)InN(n-Bu)(2)](2), triclinic space group P&onemacr; (No. 2), a = 11.943(2) Å, b = 15.790(1) Å, c = 10.711(3) Å, alpha = 98.60(1) degrees, beta = 103.54(2) degrees, gamma = 94.85(1) degrees, V = 1926 Å(3), rho(calcd) = 1.232 g cm(-)(3). Mass spectrometry data indicate that both compounds exist as dimers in the gaseous state.
