Tris-(m-tolyl)-phosphonium-9-fluorenylid, also known as P(m-tol)3-9-fluorenylid, is a phosphonium salt that serves as a versatile organocatalyst in various chemical reactions. It is composed of a phosphonium cation with three m-tolyl (3-methylphenyl) groups attached to the phosphorus atom and a 9-fluorenylide anion. Tris--phosphonium-9-fluorenylid is particularly effective in promoting asymmetric reactions, such as the Michael addition and the Mannich reaction, due to its ability to activate electrophiles and stabilize transition states. Its unique structure allows for the formation of strong hydrogen bonds and ion pairs, which are crucial for its catalytic activity. The use of Tris-(m-tolyl)-phosphonium-9-fluorenylid in organic synthesis has been widely reported, highlighting its potential in the development of new synthetic methods and the production of enantiomerically pure compounds.

7293-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7293-82-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.Calculate Digit Verification of CAS Registry Number 7293-82:
(6*7)+(5*2)+(4*9)+(3*3)+(2*8)+(1*2)=115
115 % 10 = 5
So 7293-82-5 is a valid CAS Registry Number.
