Description
Triphenylphosphine Resin is a versatile polymer-bound reagent used in various chemical reactions, particularly in organic synthesis. It is known for its ability to facilitate a range of reactions, such as Wittig reactions, Mitsunobu reactions, esterification, isomerization, and the conversion of alcohols or carboxylic acids to corresponding chlorides.
Uses
Used in Organic Synthesis:
Triphenylphosphine Resin is used as a solid-supported reagent for the preparation of polymer-bound ylids, which are useful in Wittig reactions. This application aids in the formation of various complex organic molecules.
Used in Mitsunobu Reactions:
In the Mitsunobu reaction, triphenylphosphine resin serves as a better alternative to triphenylphosphine, enhancing the efficiency and selectivity of the reaction.
Used in Esterification:
Triphenylphosphine Resin is used as a catalyst for the esterification of alkylphosphonic acids using primary alcohols in the presence of iodine and imidazole, facilitating the formation of ester compounds.
Used in Conversion Reactions:
The resin is employed to catalyze the conversion of 3-[3-(1,3-dioxolan-2-yl)-1-hydroxypropyl]pyridine to 3-[1-bromo-3-(1,3-dioxolan-2-yl)propyl]pyridine using carbon tetrabromide, as well as the isomerization of (Z)-nitro olefins to the (E)-isomers.
Used in Alcohol and Carboxylic Acid Conversion:
Triphenylphosphine Resin is used to convert alcohols or carboxylic acids to the corresponding chlorides, which are essential intermediates in organic synthesis.
Used in Amide Formation:
In combination with carbon tetrachloride, the resin is used for the coupling of N-alkoxycarbonyl α-amino acids and primary amines to form the corresponding amides, which are crucial in the synthesis of peptides and other biomolecules.
Check Digit Verification of cas no
The CAS Registry Mumber 39319-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,3,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39319-11:
(7*3)+(6*9)+(5*3)+(4*1)+(3*9)+(2*1)+(1*1)=124
124 % 10 = 4
So 39319-11-4 is a valid CAS Registry Number.
