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(C8H8)[R = Ph2C(C5H4N-2)].Keywords
