Dimethylindium dialkylamides and organylphosphides, X-ray crystal structure of (Me2InNR2)2 (R = Et, Pri, SiMe3) and (Me2InPBut2)2

Synthesis and Molecular Structure Studies of [Me2AlN(i-Pr)CH2Ph]2 and the Related Orthometalated Dimers [RAlN(i-Pr)-μ-(CH2C6H4)]2, where R = Me, n-Pr, n-Bu, i-Bu

“…These data are consistent with those reported for cis -[Me 2 AlN(H) i -Pr] 2 , cis -[Me 2 AlN(Me)CH 2 Ph] 2 , and [Me 2 AlN(C 6 H 11 ) 2 ] 2 , with fold angles of 15.5°, 20.4°, and 27.4°, respectively. The molecular structure data for 1a are in agreement with published data and correlations of the steric properties of functional groups attached to the amine nitrogen with the corresponding dimer geometries. ,,− ,− …”

“…Our results are in agreement with those of Bradley 10 in that the influence of R‘ is more important than that of R and that the effect is primarily steric in nature. Mass spectral studies on the related series [Me 2 InNR‘ 2 ] 2 and on [Me 2 AlN(CH 2 Ph) 2 ] 2 and [Me 2 AlN(H)CH 2 Ph] 2 , suggest that the dimers become less stable in the vapor phase with increasing steric bulk of the R‘ group.…”

Chemistry of Indium(III) Tris(cyclopentadienide). Reactions with Diphenylphosphine,tert-Butyl Alcohol, and Acetylacetone. Cyclopentadiene and Reductive Elimination Reactions

“…However, as the elimination of the first molecule of cyclopentadiene from In(C 5 H 5 ) 3 and HPPh 2 was observed to be slow, especially slow when compared to the cyclopentadiene elimination reaction between Me 2 In(C 5 H 5 ) and HPPh 2 , a second elimination of C 5 H 6 would be most unlikely. The formation of Me 2 InPPh 2 from Me 2 In(C 5 H 5 ) and HPPh 2 was complete within 15 min of warming the solution from −196 °C to room temperature, according to NMR spectral studies, whereas a mixture of In(C 5 H 5 ) 3 and HPPh 2 required a significantly longer time for complete reaction. As the elimination of the first molecule of C 5 H 6 is slow, the elimination of the second molecule of cyclopentadiene is expected to be even slower, according to previous observations of elimination reactions in group 13 chemistry .…”

Photoinduced Reactions of Tri-tert-butylindium with (Diethylamino)trimethylstannane and (Di-n-butylamino)trimethylstannane

“…The average In−C bond length (2.251(6) Å) in [( t -Bu) 2 InNEt 2 ] 2 is slightly longer than the average bond length (2.217(5) Å) in [( t -Bu) 2 In( n -Bu) 2 ] 2 . However, many of the bond lengths and bond angles common to [( t -Bu) 2 InNEt 2 ] 2 and [Me 2 InNEt 2 ] 2 differ significantly (Table ). The In−N bond in [( t -Bu) 2 InNEt 2 ] 2 (average 2.270 (4) Å) is slightly longer than the In−N bond in [Me 2 InNEt 2 ] 2 (average 2.235 (3) Å).…”
