There total 1 articles about cis-W(CO)4(PMePh₂)(2,3-dihydrothiophene) 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: 50.0%

2,3-dihydrothiophene (1120-59-8) + [(methyl)diphenylphosphine]pentacarbonyltungsten(0) (18534-36-6) → cis-W(CO)4(PMePh2)(2,3-dihydrothiophene) (119638-31-2)

Guidance literature:

In tetrahydrofuran; pentane; byproducts: cis-W(CO)4(PMePh2)2; Irradiation (UV/VIS); (N2); a THF soln. of W complex was irradiated (254 nm) for 2 h, to mixt. was added pentane soln. of dihydrothiophene and stirred for 30 min, then soln. was concd.; pentane was added and mixt. was stored for 3 d at -20°C; compd. was obtained as dark green oil;

Reference yield:

cis-W(CO)4(PMePh2)(2,3-dihydrothiophene) (119638-31-2) → W(CO)4(PMePh2)2 (123538-03-4) + [(methyl)diphenylphosphine]pentacarbonyltungsten(0) (18534-36-6)
