Investigations into the Reactivity of Organoelement Gallium Subhalides – Syntheses of Bifunctional Digallium Carboxylate Iodides Possessing Bridged Ga–Ga Bonds and Terminal Iodine Atoms

Abstract: Keywords: Gallium / Subvalent compounds / Subhalides / Metal-metal bonds / Carboxylato ligands The organoelement subhalide R 2 Ga 2 I 2 (1) [R = C(SiMe 3 ) 3 ] reacted with one equivalent of different lithium carboxylates LiO 2 CR [R = -C 6 H 5 , -4-Me 3 C-C 6 H 4 , -4-BrC 6 H 4 , -3,5-Me 2 C 6 H 3 , -CMe 3 ] by the selective replacement of only one iodine atom. Bifunctional digallium compounds were formed, in which one chelating carboxylato group bridges the Ga-Ga bonds. Thus, both gallium atoms are coordinat… Show more

“…As is apparent from Table 8, relatively few structures of this class have published been since 1999. [138][139][140][141][142][143][144][145][146] The relative paucity of the recent structural data is borne out by a comprehensive review of gallium(III) and indium(III) alkoxides and aryloxides published in 2006. 147 As before, derivatives with bonding between the two light atoms boron and oxygen are not considered.…”

“…Interessanterweise bleiben die Ga–Ga‐Bindungen selbst unüberbrückt. Dies steht im Gegensatz zu Beobachtungen aus früheren Untersuchungen, in denen mit Digalliumdicarboxylaten (siehe Einleitung) oder selbst gemischten Halogenocarboxylatodigallium‐Verbindungen 11 immer eine Überbrückung der Element–Element‐Bindung beobachtet wurde. Aus dieser besonderen Situation resultieren in den hier beschriebenen Verbindungen ( 2 und 4 bis 10 ) relativ lange Ga–Ga‐Bindungen (245 pm im Durchschnitt, Tabelle 1).…”

“…The reaction of the subhalide Ga 2 I 2 [C(SiMe 3 ) 3 ] 2 with lithium dibenzoylmethamide affords a mixture of products, one of them being GaI[C(SiMe 3 ) 3 ](benzoate), wherein the only gallium atom has coordination number four. 219…”
