4442-41-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4442-41-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4442-41:
(6*4)+(5*4)+(4*4)+(3*2)+(2*4)+(1*1)=75
75 % 10 = 5
So 4442-41-5 is a valid CAS Registry Number.

Catalytic Activity of an Octopus-type Calixarene on the Formation of Ethers

Taniguchi, Hisaji,Nomura, Eisaku

, p. 1773 - 1776 (1988)

5,11,17,23,29,35-Hexa-p-tert-butyl-37,38,39,40,41,42-hexakis-(3,6,9-trioxadecyloxy)calixarene catalyzes the formation of an ether and bisphenoxymethanes through the Williamson synthesis.

NHC-CDI Betaine Adducts and Their Cationic Derivatives as Catalyst Precursors for Dichloromethane Valorization

Sánchez-Roa, David,Mosquera, Marta E. G.,Cámpora, Juan

, p. 16725 - 16735 (2021/11/18)

Zwitterionic adducts of N-heterocyclic carbene and carbodiimide (NHC-CDI) are an emerging class of organic compounds with promising properties for applications in various fields. Herein, we report the use of the ICyCDI(p-Tol) betaine adduct (1a) and its cationic derivatives2aand3aas catalyst precursors for the dichloromethane valorization via transformation into high added value products CH2Z2(Z = OR, SR or NR2). This process implies selective chloride substitution of dichloromethane by a range of nucleophiles Na+Z-(preformed or generatedin situfrom HZ and an inorganic base) to yield formaldehyde-derived acetals, dithioacetals, or aminals with full selectivity. The reactions are conducted in a multigram-scale under very mild conditions, using dichloromethane both as a reagent and solvent, and very low catalyst loading (0.01 mol %). The CH2Z2derivatives were isolated in quantitative yields after filtration and evaporation, which facilitates recycling the dichloromethane excess. Mechanistic studies for the synthesis of methylal CH2(OMe)2rule out organocatalysis as being responsible for the CH2transfer, and a phase-transfer catalysis mechanism is proposed instead. Furthermore, we observed that1aand2areact with NaOMe to form unusual isoureate ethers, which are the actual phase-transfer catalysts, with a strong preference for sodium over other alkali metal nucleophiles.

An efficient method for the preparation of dialkoxymethanes from dichloromethane with alcohols catalyzed by a Cu-NHC complex

Zhan, Lewu,Pan, Renming,Xing, Ping,Jiang, Biao

supporting information, p. 4036 - 4038 (2016/08/18)

A facile, rapid and efficient method for the preparation of dialkoxymethanes from dichloromethane with alcohols catalyzed by a Cu-NHC complex is reported. A variety of symmetrical dialkoxymethanes can be prepared under mild condition in excellent yields (up to 98%). The unsymmetrical ether is also obtained in 89% yield from the etherification of p-tolylmethanol and n-butyl chloride catalyzed by ICyCuCl complex at 80?°C. The reaction provides a new method for the preparation of dialkoxymethanes under mild conditions in excellent yields.

Synthesis of carbonates directly from 1 atm CO2 and alcohols using CH2Cl2

Yamazaki, Yusuke,Kakuma, Kasumi,Du, Ya,Saito, Susumu

scheme or table, p. 9675 - 9680 (2011/02/24)

We introduced here a new one-pot, general procedure for the preparation of dialkyl carbonates from alcohols in a straightforward fashion under 1 atm pressure of CO2 using Cs2CO3 and CH 2Cl2 as key reagents.
