A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have a hydrogen atom at the α-position, using a hydroperoxide as an oxidizer and an iodide salt as a catalyst precursor, thereby introducing an acyloxy group derived from the carboxylic acid into the α-position of the carbonyl compound.

longer n-alkyl; X = Cl, Br, or I) are shown by i.r. and Raman spectroscopy to contain the halide-bridged dimeric anions [Cd2X6]2– both in the solid state and when dissolved in non-complexing solvents. Recent conclusions on the nature of the mixed-halide systems [NPrn4]x[(CdX2Y)x] are shown to be questionable. Previous assignments for the anions [CdX4]2– have been augmented from studies on [NR4]2[CdX4]
盐[NR 4 ] x [(CdX 3)x ](R = Pr n或更长的正烷基; X = Cl,Br或I)通过ir和拉曼光谱法显示含有卤化物桥联的二聚阴离子[ Cd 2 X 6 ] 2 –呈固态,也可溶于非复杂溶剂中。关于混合卤化物体系[NPr n 4 ] x [(CdX 2 Y)x ]的性质的最新结论表明是可疑的。阴离子[CdX 4 ] 2–的先前分配已从对[NR 4 ]的研究中扩充2 [CdX 4 ]。
