Abstract

Cocondensation of calcium, strontium, or barium vapours with excess cot (cyclo-octatetraene) and thf (tetrahydrofuran) affords sparingly thf-soluble, pyrophoric M(cot)(thf)_n (1), which decomposes at ca. 60 °C in vacuo to M(cot) (2), M = Ca, Sr, or Ba; reactions of (2) with some organic halides are reported along with formation of a pyridine adduct, M(cot)(pyridine)_n (3), and from (2) and RPCl₂ the synthesis of a thermally stable phosphacyclopropane, RP(C₈H ₈) [R = Ph₂C(C₅H₄N-2)].
