Tetraethylammonium Bromochromate, TEABC, Tetrahexylammonium Bromochromate, THexABC and Tetraheptylammonium Bromochromate, THepABC are new reagents used for almost quantitative conversion of alcohols into the corresponding aldehydes and ketones. These tetraalkylammonium bromochromate reagents are easily synthesized by the reaction of relative tetraalkylammonium bromide with a solution of CrO 3 in a 1:1 mole ratio. These reagents are versatile agents for the effective and nearly quantitative oxidation of organic substrates, in particular for alcohols, under mild and acid-free conditions.

Lead I 4900 Synthesis and Characterization of Two New Fluoroplumbate(II) Complexes: Tetrabutylammonium Fluorodihaloplumbate, (Bu) 4 N[PbX 2 F] (X: Cl, I). -The new title compounds are synthesized by reaction of PbCl2 or PbI2 with Bu4NF in MeCN (20°C, 24 h). The samples are characterized by IR, UV/VIS, 13 C, 1 H, and 19 F NMR spectroscopy. There is no side product and the reaction is quite fast. The accompanying color change provides visual means for ascertaining the progress of the reaction. -(JAVANSHIR, Z.; MEHRANI, K.; GHAMMAMY*, S.; SAGHATFOROUSH, L.; SEYEDSADJADI, S.; HASSANIJOSHAGHANI, A.; TAVAKOL, H.; Bull.
