PROCESS FOR THE PREPARATION OF DIORGANOMAGNESIUM COMPOUNDS |
摘要 |
A method of preparing a di-organo-magnesium compound of the formula R2Mg in which R is an organic radical bonded to Mg by carbon, comprising reacting magnesium hydride MgH2 or magnesium and hydrogen with an olefin in the presence of a catalyst comprising a compound of a transition metal of the 4th to 8th secondary group and an organometallic compound or a hydride of a metal of the 1st to 3rd principal groups of the periodic system. Advantageously there is also present a polycyclic aromatic compound or a tertiary amine as activator and the reaction is effected in the presence of tetrahydrofuran as solvent at a pressure of about 1 to 300 bars at about 0 DEG to 200 DEG C., the atomic ratio of Mg:transition metal being from about 104 to 10:1, the molar ratio of transition metal compound:organometal compound or metal hydride being from about 0.1 to 10:1, the molar ratio of olefin:magnesium being from about 2 to 10:1 and the olefin being of the formula CH2=CHR' wherein R' is H or an alkyl, cyclo-alkyl, aryl or aralkyl group. |
