Organogallium reaction with

Organogallium compounds are good nucleophiles for performing addition reactions to carbonyl functionalities. Alkylation, allylation, aldol condensation, and the Reformatsky reaction proceed readily with organogallium reagents. [Pg.724]

Aromatic hydrocarbons are alkenylated with allenylsilane in the presence of GaCl3 at — 90 °C. A modest level of 0r// 0-seleetivity is observed. Organogallium electrophiles generated from allenes and GaCl3 are active intermediates in this reaction. While the allenylsilane reacts exclusively at the central carbon, 1,2-alkadiene reacts at the terminal carbon predominantly (Scheme 151).446... [Pg.742]

The hexanuclear organogallium oxide fluoride, Mes6Ga604F4 (Mes = mesitylene) has been prepared by the reaction of Mes2GaF with water in THF at ambient temperature [14]. The structure of Mes6Ga604F4, which crystallizes with a mole ofTHF, is a distorted octahedron of Ga atoms in which all eight faces are capped by O/F... [Pg.118]

The generality of this transalkylation reaction is reflected in the successful synthesis of higher organoboron (73) and organogallium alkyls (14%) from olefins with triisobutylborane and triisobutylgallium, respectively. [Pg.75]
