1092807-68-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1092807-68-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,8,0 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1092807-68:
(9*1)+(8*0)+(7*9)+(6*2)+(5*8)+(4*0)+(3*7)+(2*6)+(1*8)=165
165 % 10 = 5
So 1092807-68-5 is a valid CAS Registry Number.

A tuned bicyclic proazaphosphatrane for catalytically enhanced n-arylation reactions with aryl chlorides

Kim, So Han,Kim, Min,Verkade, John G.,Kim, Youngjo

, p. 1954 - 1960 (2015/03/18)

The N-arylation of various amines with aryl chlorides proceeded in good-to-excellent yields in the presence of P[N{(p-NMe2)C6H4CH2}CH2CH2]3N (1e, a new electron-rich proazaphosphatrane ligand) and small amounts of Pd2(dba)3 (dba = dibenzylideneacetone). This catalytic system was also very effective for the synthesis of carbazoles. An efficient palladium-catalyzed N-arylation reaction of amines under mild conditions with a tuned bicyclic proazaphosphatrane has been developed.

Page/Page column 15, (2009/01/24)

The present invention provides a carbazole compound represented by the following formula (I): wherein each Ar1 independently represents a substituted or unsubstituted monovalent aromatic group or an aromatic group containing a heteroring, and R1 and each R2 independently represent a hydrogen atom, an alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group.
