Diaethyl-bis-(N-methyl-anilino)-phosphonium-iodid, also known as DEBMAP-I, is a phosphonium salt that serves as a versatile and efficient catalyst in various organic reactions. It is characterized by its ability to activate carbonyl compounds, promoting nucleophilic addition reactions and facilitating the formation of carbon-carbon and carbon-heteroatom bonds. DEBMAP-I is particularly noted for its stability, ease of handling, and low toxicity, making it a preferred choice over traditional metal-based catalysts in many synthetic applications. Its structure, featuring a central phosphorus atom bonded to two ethyl groups and two N-methyl-aniline groups, with an iodide counterion, contributes to its unique reactivity and selectivity in catalytic processes.
The CAS Registry Mumber 5611-55-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,1 and 1 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5611-55: (6*5)+(5*6)+(4*1)+(3*1)+(2*5)+(1*5)=82 82 % 10 = 2 So 5611-55-2 is a valid CAS Registry Number.
