131291-63-9

4-Methyl-2-phenyl-6-(pyrazol-1-ylmethyl)pyrimidine is a ligand that preferentially forms a cyclopalladated regioisomer with tridentate coordination when reacted with lithium tetrachloropalladate, demonstrating its ability to influence the cyclopalladation process through its structural features. This behavior contrasts with related ligands that undergo mono- or mixed cyclopalladation, highlighting the role of substituent positioning in determining metallation outcomes.

131291-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131291-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131291-63:
(8*1)+(7*3)+(6*1)+(5*2)+(4*9)+(3*1)+(2*6)+(1*3)=99
99 % 10 = 9
So 131291-63-9 is a valid CAS Registry Number.

Cyclometallated compounds VI. Cyclopalladation of 2-phenylpyrimidines with pendant pyrazole donors

Caygill, Graham B.,Steel, Peter

, p. 375 - 381 (2007/10/02)

The use of pendant pyrazole groups to induce double cyclopalladation of 2-phenylpyrimidines has been investigated. 4,6-Bis(pyrazol-1-yl)-2-phenylpyrimidine undergoes monocyclopalladation only, whilst 4-methyl-2-phenyl-6(pyrazol-1-ylmethyl)pyrimidine react
