3857-83-8 Usage
Uses
2-Naphthyl trifluoromethanesulfonate (2-naphthyl triflate) may be used as an arylating agent in the arylation of 1-(methoxycarbonyl)-2,5-dihydropyrrole by Heck reaction. It may be used as a substrate for coupling with Reformatsky reagent BrZnCH(CH3)(COOtC4H9) in the presence of “reduced” dichlorobis(1,1-diphenylphosphino)ferrocene catalyst.
General Description
2-Naphthyl trifluoromethanesulfonate (2-naphthyl triflate) is an aryl triflate. Its ruthenium-catalyzed conversion to 2-bromonaphthalene has been reported.
Check Digit Verification of cas no
The CAS Registry Mumber 3857-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3857-83:
(6*3)+(5*8)+(4*5)+(3*7)+(2*8)+(1*3)=118
118 % 10 = 8
So 3857-83-8 is a valid CAS Registry Number.

Metal-catalyzed amination of organic sulfonates to organic amines
-
, (2008/06/13)
A process of preparing an organic amine having at least one unsaturated group, such as an arylamine, involving contacting an unsaturated organic sulfonate, such as an aryl sulfonate, with a reactant amine, such as an alkyl or aryl amine, in the presence of a base and a transition metal catalyst under reaction conditions. The transition metal catalyst contains a Group 8 metal and a chelating ligand, for example a Group 15-substituted arylene or Group 15-substituted metallocene, such as 1,1'-bis(diphenylphosphino)-2,2'-binaphthyl or 1,1'-bis(diphenylphosphino)-ferrocene, respectively. The aryl sulfonate can be prepared from a phenol and sulfonating agent.
