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
carbon monoxide;
In
dichloromethane;
(dry N2); Co(C5H5)2 (0.85 mmol) added to soln. of RhBr2(P(OCH3)3)(C5Ph5)(0.38 mmol) satd. with CO; soln. evapd.; extn. (toluene); chromy. (alumina, CH2Cl2/n-hexane): elution (1/10) gave small quantity of Rh(CO)2(C5Ph5); further elution (1/3);this eluate partially evapd. in vac. to give Rh(CO)(P(OCH3)3)(C5Ph5) asa solid; elem. anal.; mass spectrum;

In
tetrahydrofuran;
under Ar: addn. of 2.73 mmol NaC5(C6H5)5 in THF to 1.36 mmol (Rh(CO)2Cl)2 with stirring; stirring for 24 h at room temperature;; evaporation to dryness; extraction the residue with 50°C warm toluene; in air: concn.; chromy. (silica gel, toluene); evaporation; twicerecrystallization from boiling heptane;;

With
zinc;
In
tetrahydrofuran;
(dry N2); mixt. of (RhCl(CO)2)2 (0.26 mmol), C5Ph5Br (0.57 mmol), and zinc dust (0.62 mmol), in THF stirred for 4 h; mixt. filtered; filtrate evapd.; extn. (CH2Cl2); column chromy. (alumina, CH2Cl2/n-hexane): elution (1/6) gave Rh(CO)2L (eluate evapd.; elem. anal. and mass spectrum), further elution (1/3) gave small quantities of (Rh(CO)L)2 (eluate evapd.);
