26926-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26926-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,2 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26926-51:
(7*2)+(6*6)+(5*9)+(4*2)+(3*6)+(2*5)+(1*1)=132
132 % 10 = 2
So 26926-51-2 is a valid CAS Registry Number.

Palladium-Catalyzed Regiodivergent Substitution of Propargylic Carbonates

Locascio, Theresa M.,Tunge, Jon A.

, p. 18140 - 18146 (2016/12/16)

The palladium(0)-catalyzed, ligand-controlled, regioselective addition of diaryl acetonitrile pronucleophiles to propargylic carbonates is reported. Selective formation of either terminal 1,3-dienyl or propargylated products is proposed to arise from a change in reaction mechanism controlled by the denticity of the coordinating ligand.

AROMATIC NUCLEOPHILIC SUBSTITUTION ON η6-Cr(CO)3-COMPLEXED HALOGENOARENES: ARYLATION OF SECONDARY CARBANIONS

Baldoli, Clara,Buttero, Paola Del,Licandro, Emanuela,Maiorana, Stefano

, p. 409 - 414 (2007/10/02)

The paper deals with the aromatic nucleophilic substitution on η6-Cr(CO)3-complexed fluorobenzene and ortho-, meta-, and para-dichlorobenzenes with stabilized carbanions, both under phase-transfer conditions (PTC) and in DMSO solution.In the case of the η6-Cr(CO)3-complexed ortho-, meta-, and para-dichlorobenzenes only one chlorine atom is replaced by the carbanions.
