42068-12-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42068-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,6 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42068-12:
(7*4)+(6*2)+(5*0)+(4*6)+(3*8)+(2*1)+(1*2)=92
92 % 10 = 2
So 42068-12-2 is a valid CAS Registry Number.

Immobilization of Heteroleptic Bis(oxazoline) Zinc Catalysts on SBA-15 for Asymmetric Hydrosilylation

Le Roux, Erwan,De Mallmann, Aimery,Merle, Nicolas,Taoufik, Mostafa,Anwander, Reiner

, p. 5146 - 5154 (2015)

The C2-symmetric bis(oxazoline)s (4S,4S)-R1-BOX, with R1 = tBu and Ph, react with ZnEt2 straightforwardly to the four-coordinate complexes ((4S,4S)-R1-BOX)ZnEt2 in high yield. Their immobil

A highly enantioselective hydrogenation of silyl enol ethers catalyzed by chiral frustrated lewis pairs

Wei, Simin,Du, Haifeng

, p. 12261 - 12264 (2014/10/16)

Using a simple combination of tri-tert-butylphosphine and chiral borane generated in situ by the hydroboration of chiral diene with HB(C 6F5)2 as a frustrated Lewis pair catalyst, a highly enantioselective metal-free hydrogenation of silyl enol ethers was successfully realized to furnish a variety of optically active secondary alcohols in 93-99% yields with 88->99% ees.

Iron-catalysed reduction of olefins using a borohydride reagent

Carter, Tom S.,Guiet, Lea,Frank, Dominik J.,West, James,Thomas, Stephen P.

supporting information, p. 880 - 884 (2013/05/08)

The iron-catalysed reduction of olefins has been achieved using a simple iron salt and sodium triethylborohydride. A wide range of mono- and trans-1,2-disubstituted alkenes have been reduced (91-100%) using 25 mol% iron(II) triflate, 1 mol% N-methyl-2-pyrrolidinone and 4 equivalents of sodium triethylborohydride. The reduction of alkynes to alkanes is also reported (up to 84%). Significantly, the reduction of trisubstituted alkenes has also been achieved (60-86%). Copyright
