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.

Organoindium Thiolate Oligomers: An X-ray Structural Study

“…Bis(tricyclohexyltin) sulfide (Aldrich), 2-methylpropane-2-thiol (Aldrich), 4,6-dimethyl-2-mercaptopyrimidine (Aldrich), cyclopentanethiol (Aldrich), cyclohexanethiol (Aldrich), 2,5-dimethylbenzenethiol (Aldrich), and 2,6-methylbenzenethiol (Aldrich) were purchased and used as received. Trimethylindium etherate and tri- tert -butylindium were prepared according to the published procedures. , The compounds are both water- and oxygen-sensitive; therefore, standard Schlenk line and glovebox techniques were employed. All of the glassware used in the synthetic work was oven- and/or flame-dried.…”

Sterically crowded diolates of group 13 metals

“…{ t BuAl[OC(CH 3 ) 2 CH 2 C(CH 3 ) 2 O]} 2 , t Bu 3 Ga and t Bu 3 In were synthesised as described in the literature [6,18,19]. 1 H and 13 C NMR spectra were run on a Mercury-400BB spectrometer.…”

Addition of in situ reduced amidinato-methylaluminium chloride to acetylenes

“…15% ate complex 3 identified by NMR and XRD. In the reaction mixture, aluminium amidinate 3 was accompanied by major by-products Me 3 SnSnMe 3 (−109 ppm in the 119 Sn NMR spectrum) 14 and L 2 AlMe (L = DippNC(Me)NDipp). 13 This structural arrangement on the aluminum atom is not entirely surprising.…”
