Synthese und Charakterisierung chiraler Organogallium- und -aluminiumalkoholate mit intramolekularer Stickstoffstabilisierung. Röntgenstrukturanalyse von Dimethylgallium-(S)-2-dimethylamino-3-methyl-1-butanolat, Dimethylgallium-(S)-2-dimethylamino-3-phenyl-1-propanolat und Dimethylgallium-(R)-2-dimethylamino-1-butanolat

Synthesis, AACVD and X-ray crystallographic structures of group 13 monoalkoxometallanes

“…The In(1)-O(2) distance of 2.504(5) Å in 2 can be attributed to O→In dative bonding, although interestingly it is shorter than the corresponding axial Ga(1)-O(2) distance in compound 1.The structures of compounds 1 and 2 are similar to related compounds of the type [R' 2 M(µ-OR)] 2 (R = donor functionalized group), which have been previously reported and all bond lengths and angles are comparable[14,[18][19][20][21].…”

“…A range of diorganoalkoxometallanes of gallium and indium incorporating donor-functionalised alkoxides have been structurally characterised [12,14,[16][17][18][19][20][21]. In general, these compounds are synthesized either via the reaction of MR' 3 with an alcohol, or from the salt metathesis reaction of R' 2 MX and M'OR (M = Ga, In; M' = alkali metal, R' = Me, Et, X = halide) [1].…”

Syntheses, X-ray structures and CVD studies of diorganoalkoxogallanes

“…In the related indium complex [Me 2 In(OCH(CH 2 NMe 2 ) 2 )] 2 incorporating the same aminoalkoxide ligand, the indium atom is six-coordinate since both NMe 2 groups coordinate to the larger indium atom [19]. Some related methylalkoxogallanes, such as [Me 2 Ga(OCH 2 CH(R)NMe 2 )] 2 (R = i Pr, Bz, Et) have been previously reported with comparable bond lengths and angles to 1-4 [26][27][28].…”

Molecular precursors to gallium oxide thin films

“…It is assumed that 1-5 would adopt dimeric structures similar to related complexes, such as [Me 2 Ga{l-OCH 2 CH(R)NMe 2 }] 2 (R = Pr i , Bz, Et) that have been previously reported. 18 Thus, compounds 1-5 are thought to exist as dimers containing a M 2 O 2 four-membered ring, as shown in Scheme 1. A dative ligand-metal interaction in 1-5 is confirmed by a comparison of proton resonances of the alkoxide ligand in the product to the free ligand.…”

“…11,12 A series of dimeric dialkylgallium alkoxides, [Me 2 Ga(OR)] 2 , have been reported and a number have been structurally characterised. [18][19][20] However, monoalkylgallium bisalkoxides, [RGa(OR) 2 ] 2 , reported in the literature to date are limited. 21,22 Attempts to prepare these complexes using simple monofunctional alkoxides have failed and generally result in the formation of dialkylgallium alkoxides or sesquialkoxides.…”
