Abstract

Group XIII elements are among the most useful metals for synthetic organic chemistry. Yet, the use of gallium compounds in organic chemistry has so far rarely been studied. In a recent study, gallium(III) chloride was used for thioacetal activation, 1 vinylation reaction, 2 isocyanide cycloaddition, 3 allylation reaction, 4 and acetal activation. 5 However, the utilization of gallium(II) chloride has mostly been limited to the reductive Friedel–Crafts reaction. 6 ...
