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:
- Guidance literature:
-
In
tetrahydrofuran;
byproducts: LiI; to (C6H5)3SnLi in THF dropped under stirring CS2 in slight excess, colour change to red with warming, after cooling addn. of (CH3)2CHI in excess; column chromy. (silica gel/THF), solvent removed from the violet fraction, treated with ethanol, pptn., recrystd. from petroleum ether, elem. anal.;
- Guidance literature:
-
In
tetrahydrofuran;
react. of ester and metal carbonyl (excess) under N2 in the dark, 2h; reducing volume; chromy. (silica gel, THF/petroleum ether); evapn.; freezing in methanol; crushing; vigorously stirring up to room temp.; filtration; washing (methanol); drying; subliming off excess metal carbonyl; elem. anal.;
