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:
-
With
chloro(1,5-cyclooctadiene)rhodium(I) dimer; trisodium tris(3-sulfophenyl)phosphine; sodium carbonate;
In
methanol; water;
at 25 ℃;
for 48h;
Under more vigorous conditions (100 deg C, 16 h) double substitution occured giving a mixture of three isomers (derived exclusively from the attack of the monosubstituted double bond of isoprene) in quantitative yield.;
