Abstract: | The heavy alkaline earth elements calcium, strontium and barium react with two equivalents of N,N’-bis(2,6-diphenyl)formamidine (DippFormH) in the presence of bis(pentafluorophenyl)mercury to afford the bis(formamidinate) species [M(DippForm) ₂ (THF)n](M = Ca, n = 1 ( 1), M = Sr ( 2) or Ba ( 3), n = 2) in good to moderate yield. Use of one equivalent of DippFormH during the preparation of 1–3 putatively results in the formation of the organoamide heavy alkaline earth Grignard species “[(X)M(DippForm)]”(M = Ca, Sr or Ba, X = F or C₆F₅). These compounds participate in the nucleophilic substitution of the para-fluorine of pentafluorobenzene, a by-product of prior ligand exchange, to render DippForm(4-HC₆F₄). |
