Technology Process of Germane, trichloro(chloromethyl)-

There total 1 articles about Germane, trichloro(chloromethyl)- 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: 1.6%

germanium (7440-56-4) + dichloromethane (75-09-2) → germaniumtetrachloride (10038-98-9) + trichloro(chloromethyl)germane (21572-18-9)

Guidance literature:

In gas; vaporization of Ge (alumina-coated tungsten crucible, 1200-1300°C, 5E-3 Torr), introduction into reaction flask (cooled with liq. N2 during Ge vaporization) together with vapor of org. halide, warming to room temp., standing for 1.5 h; GC-MS, GLC;

DOI:10.1246/bcsj.61.1247

Reference yield: 90.0%

ortho-tolylmagnesium bromide (932-31-0) + trichloro(chloromethyl)germane (21572-18-9) → dichloro(chloromethyl)(o-tolyl)germane (147330-99-2)

Guidance literature:

In diethyl ether; addn. of org. compd. to soln. of Ge-compd. in dry ether with stirring (0°C), stirring (0°C, 1 h), refluxing (1 h); addn. of hexane, keeping (overnight, room temp.), filtration, evapn., distn. of residue;

DOI:10.1246/bcsj.66.664

Reference yield: 89.0%

N,N-dimethyl-2-phenyl-2-(trimethylsilyloxy)acetamide (917077-20-4) + trichloro(chloromethyl)germane (21572-18-9) → N,N-dimethyl-O-[dichloro(chloromethyl)germyl]amygdalamide

Guidance literature:

In benzene; byproducts: (CH3)3SiCl; trichloro(chloromethyl)germane added to stirred soln. of amide in benzene; mixt. refluxed for 1 h; cooled; kept at room temp. for 3 ds; soln. concd.; hexane added; crystals filtered off; recrystd. (benzene/hexane, 4:3); elem. anal.;
