456-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 456-43-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 456-43:
(5*4)+(4*5)+(3*6)+(2*4)+(1*3)=69
69 % 10 = 9
So 456-43-9 is a valid CAS Registry Number.

9-Borabicyclo[3.3.l]nonane-induced Friedel-Crafts benzylation of arenes with benzyl fluorides

Guo, Jing,Bamford, Karlee L.,Stephan, Douglas W.

supporting information, p. 5258 - 5261 (2019/06/07)

Friedel-Crafts benzylation of arenes with benzyl fluorides using 9-borabicyclo[3.3.l]nonane (9-BBN) as a mediator has been developed. This provides a simple and cheap route to the activation of C-F bonds to synthesize 1,1-diarylmethanes in good to excellent yields (up to 98%) under mild conditions. Functional group tolerance and the mechanism are considered.

Halogenation through Deoxygenation of Alcohols and Aldehydes

Chen, Jia,Lin, Jin-Hong,Xiao, Ji-Chang

supporting information, p. 3061 - 3064 (2018/05/28)

An efficient reagent system, Ph3P/XCH2CH2X (X = Cl, Br, or I), was very effective for the deoxygenative halogenation (including fluorination) of alcohols (including tertiary alcohols) and aldehydes. The easily available 1,2-dihaloethanes were used as key reagents and halogen sources. The use of (EtO)3P instead of Ph3P could also realize deoxy-halogenation, allowing for a convenient purification process, as the byproduct (EtO)3Pa?O could be removed by aqueous washing. The mild reaction conditions, wide substrate scope, and wide availability of 1,2-dihaloethanes make this protocol attractive for the synthesis of halogenated compounds.

FLUORINATION OF HALOGENO ALCOHOLS WITH 1,1,2,3,3,3-HEXAFLUOROPROPYL DIETHYLAMINE

Watanabe, S.,Fujita, T.,Usui, Y.,Kimura, Y.

, p. 135 - 142 (2007/10/02)

Fluorination of halogeno alcohols with 1,1,2,3,3,3-hexafluoropropyl diethylamine (PPDA) was investigated. 2-Bromo-1-fluorobutane was obtained from the reaction of PPDA and 2-bromo-1-butanol (yield 50percent).Similar results were obtained from other alipha
