摘要

Stabilization of potassium triethylboranate can be achieved in solution as well as in the solid state with tridentate 1,3,5-trimethyl-1,3,5-triazinane (tmta) as dimeric [(tmta)K(μ-H)BEt3]2 (1). The metathesis reaction of the post-Grignard reagent [2,6-(tol)2C6H3-Ca(thf)3I] (2) with potassium triethylboranate yields an unusual hydrogen bridged organocalcium contact ion pair as hydrocarbon soluble [(thf)(dme)Ca(CsH3-2,6-tol2)HBEt3] (3) which shows no tendency to dismutate to the homoleptic derivatives.
