136667-01-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136667-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,6 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136667-01:
(8*1)+(7*3)+(6*6)+(5*6)+(4*6)+(3*7)+(2*0)+(1*1)=141
141 % 10 = 1
So 136667-01-1 is a valid CAS Registry Number.

Large rate accelerations in the stille reaction with tri-2-furylphosphine and triphenylarsine as palladium ligands: mechanistic and synthetic implications

Farina, Vittorio,Krishnan, Bala

, p. 9585 - 9595 (1991)

The effect changing the palladium ligands on the rates of typical Stille cross-coupling reactions was studied. Large rate enhancements (typically 102-103 over triphenylphosphine-based catalysts) were observed with tri-2-furylphosphine (TFP) and triphenylarsine, which are recommended as the new ligands of choice in the palladium-catalyzed coupling between olefinic stannanes and electrophiles. On the basis of the evidence presented, the transmetalation, which is the rate-determining step in the catalytic cycle, is postulated to involve a π-complex between the metal and the stannane double bond. In general, ligands that readily dissociate from Pd(II) and allow ready formation of this π-complex are the ones that produce the fastest coupling rates. The utility of the new ligands is demonstrated with several synthetic examples.
