12279-09-3 Usage
Uses
Different sources of media describe the Uses of 12279-09-3 differently. You can refer to the following data:
1. Chlorobis(cyclooctene)rhodium(I),dimer can be used as a catalyst: To synthesize enantioenriched gem-diaryl sulfonates by asymmetric 1,4-addition of aryl boronic acids to α,β-unsaturated sulfonyl compounds.In direct C-arylation of N-unprotected indoles and pyrroles. In the carboxylation of arenes via C-H bond activation.
2. Chlorobis(cyclooctene)rhodium(I) dimer is an organometallic complex used as a catalyst in the arylzincation of alkynes. It is also used as a building block for other Rh-based catalysts, such as the preparation of rhodium bis(phosphinimine)pyrrole pincer carbonyl complexes for deoxygenative metathesis of CO.
Check Digit Verification of cas no
The CAS Registry Mumber 12279-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12279-09:
(7*1)+(6*2)+(5*2)+(4*7)+(3*9)+(2*0)+(1*9)=93
93 % 10 = 3
So 12279-09-3 is a valid CAS Registry Number.
