Abstract

The preparation of heterobimetallic complexes consisting of alkali and heavy alkaline earth metals remains a challenge due to limited available synthetic strategies. Here we present a new class of group 1, Ba compounds of the type [M_n(Ba(Odpp)_2+n}] (M = Na(n=l) (1), K(n=1) (2). Cs(n=1) (3), Li(n=2) (4); HOdpp = 2,6diphenylphenol) and the Lewis base adducts [Li₂(thf)₂(Ba(Odpp)₄)]·PhMe (5) and [K{Ba(Odpp)₃(diglyme)}] (6) (diglyme = [bis(2-methoxy)ethyl ether]) as the first representatives of heterohimetallic group 1. Ba species of low nuclearity. The compounds display a significant degree of metal-arene interaction, believed to be a key factor in stabilizing these highly reactive species. Obtained by solid-state direct metalation, the target compounds are available without further work-up.
