“…Experimental Section Starting Materials. Trimethylphosphine was prepared according to the method of Markham et al 13 from the reaction of MeLi (Alfa Inorganics, Beverly, Mass.,) with PC13 (Anachemia, Toronto) in an ethereal solution. The product was checked for purity by vapor pressure measurement (160 mm at 0 °C; lit.…”

The IR and Raman spectra of MesP.BCI3, Me3P.BBro, and Me3P.B13 are reported. A normal-coordinate analysis, utilizing a modified Urey-Bradley force field, supports the assignments. The values of Kpe obtained using this modified force field are consistent with the increase in relative Lewis acidity along the series BC13 < BBr3 < BI,. In all of the adducts, the P-B force constant is larger than in the corresponding PH3.BX3 species.One feature of studies of the vibrational properties of adducts containing the P-B bond has been the wide range of assigned P-B stretching freq~encies.'-~ Furthermore, significantly different values have been assi ned to the magnitude of the P-B stretching force constantP9 In our recent vibrational spectroscopic investigation of the PH3*BX3 adducts: we obtained reasonable agreement in the assignment of the P-B stretching mode and its corresponding force constant with that of an independently conducted studye9 The values of the force constant vary only slightly from adduct to adduct.

CO)SCrC(OCH3)CH3 reagiert thermisch bei Temperdturen von 60-80°C, aber auch photochemisch bei Raumtemperatur mit tertiiiren Arsinen und Stibinen YR3 (Y = As, Sb; R = CH3, C2HS, C6H5, c-C6H, I ) hauptsachlich unter CO-Abspaltung zu cis-und trans-Tetracarbonyl-(carben)-komplexen. Die Umsetzung mit tertiiiren Bismutinen verlauft dagegen nicht mehr unter CO-Substitution. In einigen Fallen (R = CH3, C2HS, c-C,Hll) lassen sich aber Pentacarbonyl(bismutin)-Komplexe isolieren. Die IR-, ' H-NMR-, ' 3C-NMR-und Massenspektren der neuen Verbindungen, sowie das Isomerisierungsverhalten der cis-bzw. trans-Tetracarbonyl-(carben)-Komplexe werden diskutiert. Transition Metal Carbene Complexes, LXXXIV" Synthesis and Isomerisation of Arsine-and Stibine-substituted cis-and trans-Tetracarbonyl(carbene)Complexes and Syntheses of Pentacarbonyl(tria1kylbismuthme) Complexes of Chromium(0) (CO)SCrC(OCH3)CH3 reacts thermally in the temperature range of 60 -80°C as well as photochemically at room temperature with arsines and stibines YR3 (Y = As, Sb; R = CH3, C2H,, C6H5, c-C6H1 mainly under splitting off of a CO-group to give cis-and trans-tetracarbonyl-(carbene) complexes. Tertiary bismuthines, however, do not react under CO-substitution. In some cases (R = CH3, C2H5, c-C,HI ,) pentacarbonyl(bismuthine) complexes can be isolated. 1. r., 'H n. m. r., 13C n. m. r., and mass spectra of the new compounds as well as the isomerisation of the cis-and trans-tetracarbonyl(carbene) complexes are discussed.
