Bidentate Lewis Acids Derived from o-Diethynylbenzene with Group 13 and 14 Functions.

ABSTRACT: Starting from 1,2-diethynylbenzene, a series of bidentate Lewis acids was prepared by means of hydrometalations, in particular hydrosilylation, hydroboration, hydroalumination and terminal metalation based on group 13 and 14 elements. In the case of terminal alkyne metalation, the Lewis-acidic gallium function was introduced using triethylgallium under alkane elimination. A total of six different Lewis acids based on a semiflexible organic scaffold were prepared, bearing -SiClMe₂ , -SiCl₂ Me, -SiCl₃ , -B(C₆ F₅ )₂ , -AlBis₂ (Bis=bis(trimethylsilyl)methyl) and -GaEt₂ as the corresponding functional units. In all cases, the Lewis acid functionalisation was carried out twice and the products were obtained i
