1224-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1224-56-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1224-56:
(6*1)+(5*2)+(4*2)+(3*4)+(2*5)+(1*6)=52
52 % 10 = 2
So 1224-56-2 is a valid CAS Registry Number.

Phase behavior of benzyltributylphosphonium salts in aromatic hydrocarbons or aqueous solutions

Ohtani,Tsuchimoto

, p. 1225 - 1232 (2001)

The solubility of benzyltributylphosphonium salt (BTBPX: X = Cl, Br, or I) in aromatic hydrocarbons was examined as a function of the temperature. The solubility curve had specific features, which were characterized by critical values corresponding to the

Long sought synthesis of quaternary phosphonium salts from phosphine oxides: Inverse reactivity approach

Vetter, Anna C.,Nikitin, Kirill,Gilheany, Declan G.

, p. 5843 - 5846 (2018/06/13)

Quaternary phosphonium salts (QPS), a key class of organophosphorus compounds, have previously only been available by routes involving nucleophilic phosphorus. We report the realisation of the opposite approach to QPS utilising phosphine oxides as the electrophilic partner and Grignard reagents as nucleophiles. The process is enabled through the crucial intermediacy of the derived halophosphonium salts. The route does not suffer from the slow kinetics and limited availability of many parent phosphines and a broad range of QPS were prepared in excellent yields.

Synthesis of phosphonium salts under microwave activation - Leaving group and phosphine substituents effects

Cvengros, Jan,Toma, Stefan,Marque, Sylvain,Loupy, Andre

, p. 1365 - 1371 (2007/10/03)

The specific nonpurely thermal effects of microwaves were evidenced according to neutral or charged leaving groups during nucleophilic substitution of benzylic electrophiles with triphenylphosphine and tributylphosphine. Microwave (MW) irradiation considerably enhanced the reactions with charged alkylating agents, especially under solvent-free conditions. Results are interpreted considering the magnitude of MW effects according to the position of the transition state along the reaction coordinates.
