40648-22-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40648-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,4 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40648-22:
(7*4)+(6*0)+(5*6)+(4*4)+(3*8)+(2*2)+(1*2)=104
104 % 10 = 4
So 40648-22-4 is a valid CAS Registry Number.

Guanidine–Copper Complex Catalyzed Allylic Borylation for the Enantioconvergent Synthesis of Tertiary Cyclic Allylboronates

Ge, Yicen,Cui, Xi-Yang,Tan, Siu Min,Jiang, Huan,Ren, Jingyun,Lee, Nicholas,Lee, Richmond,Tan, Choon-Hong

, p. 2382 - 2386 (2019/02/01)

An enantioconvergent synthesis of chiral cyclic allylboronates from racemic allylic bromides was achieved by using a guanidine–copper catalyst. The allylboronates were obtained with high γ/α regioselectivities (up to 99:1) and enantioselectivities (up to 99 % ee), and could be further transformed into diverse functionalized allylic compounds without erosion of optical purity. Experimental and DFT mechanistic studies support an SN2′ borylation process catalyzed by a monodentate guanidine–copper(I) complex that proceeds through a special direct enantioconvergent transformation mechanism.

Mild two-step process for the transition-metal-free synthesis of carbon-carbon bonds from allylic alcohols/ethers and grignard reagents

Han, Xinping,Zhang, Yanhua,Wu, Jimmy

supporting information; experimental part, p. 4104 - 4106 (2010/05/15)

Chemical Equation Represented A mild two-step process for the regioselective, transition-metal-free preparation of carbon-carbon bonds from allylic alcohols/ethers and Grignard reagents is described. This process obviates the need for the harsh deprotecti

Initiated tert-Butyl Hydroperoxide-loaded Low-temperature Autoxidation of Alkenes: Alternative Hydroperoxide Syntheses and the Preparation of a Complete Set of Reference Material

Courtneidge, John L.,Bush, Melanie,Loh, Lay-See

, p. 1539 - 1548 (2007/10/02)

A complete set of characterization data for the allylic hydroperoxides prepared from 1-methylcyclohexene and the isomeric 4-methyloct-4-enes is presented.The data relies upon the preparation of allylic hydroperoxides by tert-butyl hydroperoxide-loaded autoxidations, singlet-ene oxidations and nucleophilic substitution reactions.Appropriate allylic alcohols and relevant scission products have been prepared to support the assignments given.
