Methyl-tert.-butyl-phenyl-desyl-phosphonium-jodid, also known as MTBDPPJ, is a phosphonium salt that serves as a versatile reagent in organic synthesis. It is characterized by its ability to act as a source of the desyl cation (Ph2CHMe2+), which is a bulky, non-nucleophilic carbocation. This property makes MTBDPPJ particularly useful in reactions where a stable, non-reactive cation is required, such as in the formation of carbon-carbon bonds through Friedel-Crafts reactions or in the synthesis of complex organic molecules. The iodide counterion in MTBDPPJ allows for easy handling and purification of the reagent, making it a popular choice among chemists for various synthetic applications.

6057-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6057-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6057-81:
(6*6)+(5*0)+(4*5)+(3*7)+(2*8)+(1*1)=94
94 % 10 = 4
So 6057-81-4 is a valid CAS Registry Number.
