Technology Process of 1,1-Dimethyl-1-germacyclobutane

There total 3 articles about 1,1-Dimethyl-1-germacyclobutane which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 96.0%

magnesacyclobutane (82773-70-4) + dichlorodimethylgermanium (1529-48-2) → 1,1-dimethyl-1-germacyclobutane (21961-74-0)

Guidance literature:

With magnesium bromide; In diethyl ether; a soln. of MgBr2 in Et2O was added to magnesacyclobutane, mixt. was stirred for 30 min, Me2GeCl2 was added rapidly at room temp., stirring was continued for 1 h; water was added, ethereal layer was dried (MgSO4), ether was removed bycareful fractional distn.; >95% purity according to (1)H NMR spectroscopy and GC anal.;
