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:

In
toluene;
under N2 atm. soln. (HC(PPh2=NSiMe3)2GeCl) in toluene was added to stirred soln. (Ge(N(SiMe3)2)2) in toluene at room temp. and stirred for 2 days; volatiles were removed under reduced pressure, residue was extd. with hexane/Et2O (1:1), soln. was filtered and concd.;

With
[CH((C6H5)2PNSi(CH3)3)2Li(thf)];
In
diethyl ether;
byproducts: CH2((C6H5)2PNSi(CH3)3)2; soln. of lithium salt (with two equivs.) added to cooled (-90°C) suspn. of GeCl2*dioxane with stirring; mixt. stirred at room temp. for 18 h, then filtered; then 20 mL hexane added to filtrate, soln. concd. toabout 5 mL; mixt. stood for 5 d; elem.anal.; detd. by NMR spectroscopy, X-ray crystallography;

In
diethyl ether;
under N2 atm. soln. (HC(PPh2=NSiMe3)2Li*THF) in Et2O was added slowly at-90°C to stirred soln. GeCl2*dioxane in Et2O, temp. was raised t o room temp. and stirred for 2 days; ppt. was filtered, hexane was added to filtrate and concd. under reducedpressure;
