    Description / Table of Contents: Remarks to the Synthesis of Difluorophosphoranes. n-Butyl-bis(dimethylamino)alkyliden-phosphoranes. Complex {(CO)4FeC[OSi(CH3)3]CH=P(n—C4H9) [N(CH3)2]2}Diethylamino-diethylaminosulfanyl-difluoro-i-butyl-phosphorane 3 is formed in the synthesis of bis(diethylamino)-difluoro-i-butyl-phosphorane from the corresponding phosphane by fluorination with SF4 as a by-product. Synthesis, NMR spectra, and reactions of n-butyl-bis(dimethylamino)alkylidene phosphoranes are reported. n-Butyl-bis(dimethylamino)-trimethylsilylmethylidenphosphorane, 17, reacts with Fe(CO)5 to give the tetracarbonyliron complex 19. The result of the X-ray structural analysis of 19 is reported and discussed.

Synthese, NMR-Spektren und Reaktionen von n-Butyl(bisdimethylamino)alkylidenphosphoranen werden berichtet. n-Butyl-bis(dimethylamino)-trimethylsilylmethylidenphosphoran, 17, reagiert mit Fe(CO)5 zu dem Tetracarbonyleisen-Komplex 19. Das Ergebnis der Röntgenstrukturanalyse von 19 wird mitgeteilt und diskutiert.

    Description / Table of Contents: Preparation and Reactions of Sodium Telluride, Na2Te - Crystal Structure of [Na(CH3OH)3]2Te2Sodium telluride, Na2Te 1, is easily obtained by reaction of sodium with hexagonal tellurium in 1,2-dimethoxy-ethane in the presence of catalytic amounts of naphthalene. Upon exposure to oxygen 1 reacts with methanol forming [Na(CH3OH)3]2Te2 2, which crystal structure was determined. Compound 1, prepared in situ, can be conveniently converted into dialkyl tellurides, R2Te (R = C2H5, i-C3H7, CH2 = CH—CH2 3).
    Notes: Natriumtellurid, Na2Te 1, läßt sich auf bequeme Art und Weise aus Natrium und hexagonalem Tellur in 1,2-Dimethoxy-ethan als Reaktionsmedium in Anwesenheit katalytischer Mengen an Naphthalin gewinnen. Bei der Einwirkung von Sauerstoff auf 1 in Gegenwart von Methanol entsteht [Na(CH3OH)3]2Te2 2, dessen Kristallstruktur ermittelt wurde. In situ gewonnenes 1 kann auf einfache Weise in Dialkyltelluride, R2Te, übergeführt werden (R = C2H5, i-C3H7, CH2 = CH—CH2 3).
