- REACTION OF ALKYL BROMIDES WITH STYRENE IN THE PRESENCE OF A NICKEL CATALYST
-
Alkyl bromides enter into reaction with styrene in the presence of a nickel catalyst to form the products from substitution of the vinyl hydrogen of styrene, i.e., E-1-phenyl-1-alkenes.A high yield of E-1-phenyl-1-alkenes is promoted by the use of seconda

- SYNTHESIS AND PROPERTIES OF COVALENT TRI- AND TETRAVALENT VANADIUM
-
Reactions of VCl3*3THF with RMgX (R = Ph, CH2SiMe3, C6F5) in various ratios have been studied.The stable compounds R3V*THF (R = CH2SiMe3, C6F5) were obtained.The chemical properties of R3V*THF, R4V*2L (R = CH2Ph, L = Et2O; R = C6F5, L = THF) and (Me3SiCH2)4V were investigated.Cleavage of the vanadium-carbonium ?-bond occurs in reactions with H2O, HCl and HgCl2.The insertion of carbon dioxide into the vanadium-carbon ?-bond was investigated.A scheme for the derivatives of tri- and tetravalent vanadium is proposed.Oxidative addition to (C6F5)3V*THF by Ph3CCl and VCl3*3THF was also studied.
