61103-84-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61103-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,1,0 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 61103-84:
(7*6)+(6*1)+(5*1)+(4*0)+(3*3)+(2*8)+(1*4)=82
82 % 10 = 2
So 61103-84-2 is a valid CAS Registry Number.

Synthesis of Benzyl Alkyl Ethers by Intermolecular Dehydration of Benzyl Alcohol with Aliphatic Alcohols under the Effect of Copper Containing Catalysts

Bayguzina,Gimaletdinova,Khusnutdinov

, p. 1148 - 1155 (2018/10/24)

Synthesis of benzyl alkyl ethers was performed in high yields by intermolecular dehydration of benzyl and primary, secondary, tertiary alcohols under the effect of copper containing catalysts. The formation of benzyl alkyl ethers occurs with participation of benzyl cation.

Tandem ring-closing metathesis/transfer hydrogenation: Practical chemoselective hydrogenation of alkenes

Connolly, Timothy,Wang, Zhongyu,Walker, Michael A.,McDonald, Ivar M.,Peese, Kevin M.

, p. 4444 - 4447 (2015/01/09)

An operationally simple chemoselective transfer hydrogenation of alkenes using ruthenium metathesis catalysts is presented. Of great practicality, the transfer hydrogenation reagents can be added directly to a metathesis reaction and effect hydrogenation of the product alkene in a single pot at ambient temperature without the need to seal the vessel to prevent hydrogen gas escape. The reduction is applicable to a range of alkenes and can be performed in the presence of aryl halides and benzyl groups, a notable weakness of Pd-catalyzed hydrogenations. Scope and mechanistic considerations are presented.

Direct room-temperature lactonisation of alcohols and ethers onto amides: An "amide strategy" for synthesis

Valerio, Viviana,Petkova, Desislava,Madelaine, Claire,Maulide, Nuno

supporting information, p. 2606 - 2610 (2013/03/14)

Last-minute deal: A direct lactonisation of ethers and alcohols onto amides that proceeds at room temperature under mild conditions is reported (see scheme). This allows the effective saving of up to two unproductive, sequential deprotection operations in synthetic sequences. Mechanistic studies are described, and a new "amide strategy" that exploits the dual robustness/late-stage selective activation properties of this functional group is outlined. Copyright
