Abstract
Complexes of organomagnesium chlorides with cyclic ethers such as are described in Specifications 776,993, 777,158 and 779,100 are separated into their components by treatment with an ethylene polyether of formula R3O (CH2CH2O)xR4, wherein x is an integer from 1 to 8, R3 and R4 are the same or different and represent substituted or unsubstituted hydrocarbon groups, the permissible substituents being groups which do not react with the reactants or reaction products under the conditions of the separation procedure. The organo-magnesium chloride is of formula R2(MgCl)y wherein y is a small whole number and R2 is a substituted or unsubstituted alkyl, alkenyl, aryl, aralkyl, aralkenyl or heterocyclic radical, and when y is greater than 1, R2 is the corresponding polyvalent radical whose valency is equal to y. It may be complexed with tetrahydrofuran, tetrahydropyran, 2-methyltetrahydrofuran, 2 - ethoxytetrahydropyran, tetrahydrofurfuryl ethyl ether, dihydropyran and Nmethyl morpholine. The groups R3 and R4 in the cyclic ether are preferably C2-C5 aliphatic hydrocarbon radicals; phenyl groups or substituted phenyl groups having not more than 5 atoms in each substituting group (and not more than 3 substituting groups), or aralkyl groups which have no more than 4 carbon atoms in the alkyl group, the aryl being phenyl. Specified polyethers are diethylene glycol diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether and tetraethylene glycol dimethyl ether. In an example diethylene glycol diethyl ether is added to a solution of a complex of vinyl magnesium chloride-tetrahydrofuran in tetrahydrofuran. The tetrahydrofuran is distilled off under reduced pressure. The resulting solution may be used for the synthesis of other compounds such as, for instance, trimethyl vinyl silane (see Group IV (a)). Specifications 802,517 and 826,620 also are referred to.ALSO:Organosilanes are prepared by reacting a halosilicon compound with an organomagnesium chloride in solution in an ethylene polyether of formula R3O(CH2CH2O)xR4 wherein x is 1-8, and R3 and R4 are the same or different and represent substituted or unsubstituted hydrocarbon groups. In Example 1, vinyl magnesium chloride in diethylene glycol ether (which has displaced the tetrahydrofuran used in the preparation of the complex) is reacted with trimethylchlorosilane to give trimethylvinylsilane. Specifications 776,993, [Group IV (b)], 777,158, [Group II], 779,100, [Group IV (b)], 802,517 and 826,620 are referred to.
