In the case of the temperature-sensitive threonine, soxhlet extraction with toluene was performed at 80°C to remove R-carvone from the reaction mixture. The aqueous reaction mixture was washed three times with 25 mL of ether, and then water solvent was distilled off from the hydrochloride salt. The hydrochloride salt was transferred to a vacuum oven and dried overnight at 150 °C and 10 Torr.
Check Digit Verification of cas no
The CAS Registry Mumber 29968-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,6 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 29968-78:
(7*2)+(6*9)+(5*9)+(4*6)+(3*8)+(2*7)+(1*8)=183
183 % 10 = 3
So 29968-78-3 is a valid CAS Registry Number.

Catalytic Staudinger Reduction at Room Temperature

We report an efficient catalytic Staudinger reduction at room temperature that enables the preparation of a structurally diverse set of amines from azides in excellent yields. The reaction is based on the use of catalytic amounts of triphenylphosphine as a phosphine source and diphenyldisiloxane as a reducing agent. Our catalytic Staudinger reduction exhibits a high chemoselectivity, as exemplified by reduction of azides over other common functionalities, including nitriles, alkenes, alkynes, esters, and ketones.
Sustainable organophosphorus-catalysed Staudinger reduction

, p. 4418 - 4422 (2018/10/17)
A highly efficient and sustainable catalytic Staudinger reduction for the conversion of organic azides to amines in excellent yields has been developed. The reaction displays excellent functional group tolerance to functionalities that are otherwise prone to reduction, such as sulfones, esters, amides, ketones, nitriles, alkenes, and benzyl ethers. The green nature of the reaction is exemplified by the use of PMHS, CPME, and a lack of column chromatography.

Thermodynamic dissociation constants in various water-organic solvent mixtures are given for benzylammonium, benzyldialkylammonium, and (2-phenylethyl)ammonium ions.Deviations from the Hammett equation (Eqn. 1) are similar to those observed for carboxylic acids, but of opposite sign.The extended Hammett equation (Eqn. 3), containing the hydrophobic constant, ?, yields good correlations.Derived secondary normal sigma values are exemplified.
