Sa. Aljibori, DIRECT HIGH-YIELD SYNTHESIS OF [IR(OH)(CO)(PPH(3))(2)] FROM VASKAS COMPOUND BY PHASE-TRANSFER CATALYSIS, Journal of organometallic chemistry, 506(1-2), 1996, pp. 119-119
Treatment of Vaska's compound with 50% aqueous sodium hydroxide using
benzyl(triethyl)ammonium chloride as phase-transfer catalyst gave [Ir(
OH)(CO)(PPh(3))(2)] in high yield.
