ACETONYLTRIPHENYLPHOSPHONIUM CHLORIDE

Chemical properties

WHITE TO SLIGHTLY BEIGE FINE CRYSTALLINE POWDER

The Uses of ACETONYLTRIPHENYLPHOSPHONIUM CHLORIDE

Acetonyltriphenylphosphonium chloride is used to investigate the antimycobacterial activities of Me alkenyl quinolones. It is used as a reactant for synthesis of unsaturated esters and ketones containing multiple aromatic and heteroaromatic rings using Suzuki coupling - Wittig olefination.

The Uses of ACETONYLTRIPHENYLPHOSPHONIUM CHLORIDE

Used to investigate the antimycobacterial activities of Me alkenyl quinolones

Reactant for synthesis of:

• Unsaturated esters and ketones containing multiple aromatic and heteroaromatic rings using Suzuki coupling - Wittig olefination
• Fused oxygen and nitrogen heterocycles via regioselective cyclocondensation

Purification Methods

Recrystallise it from CHCl3/*C6H6/pet ether (b 60-80o) or by dissolving it in CHCl3 and pouring it into dry Et2O. max nm() 255(3,600), 262(3,700), 268(4,000) and 275(3,100). The iodide salt crystallises from H2O and has m 207-209o. [Ramirez & Dershowitz J Org Chem 22 41 1957.] Itisan IRRITANT and is hygroscopic. When shaken with a 10% aqueous solution of Na2CO3 (8hours) it gives acetylmethylene triphenyl phosphorane which is recrystallised from MeOH/H2O and after drying at 70o/0.1mm has m 205-206o. UV: nm() 268 (6600), 275 (6500) and 288 (5700), IR: max 1529 (s), 1470 (m), 1425 (s), max 1374 (m), 1105 and 978 (s) (cm-1).
