characterized by various spectroscopic techniques (IR, electronic, NMR ( 1 H and 51 V) and electron paramagnetic resonance (EPR)), thermal, field-emission scanning electron micrographs (FE-SEM) as well as energy dispersive X-ray (EDX) studies. The crystal and molecular structure of 3 has been determined, confirming the ONN binding mode of I . The polymer-grafted complex 4 has been used for the oxidative bromination
摘要一元三齿ONN供体配体1-(2-吡啶偶氮)-2-萘酚[Hpan(I)]与[V IV O(acac)2]在干燥的甲醇中反应生成氧化钒(IV)络合物[V IV O (acac)(pan)](1)。二氧化钒(V)络合物[VVO(pan)} 2(μ-O)2](2)通过在甲醇中空中氧化1获得。络合物2也可以直接通过[V IV O(acac)2]与I反应,然后在甲醇中进行空气氧化来直接制备。用H 2 O 2在甲醇中处理1或2,得到氧化单过氧化钒(V)络合物[VVO(O 2)(pan)(MeOH)](3)。在DMF中,5%的二乙烯基苯(PS-im)与2交联的咪唑基甲基聚苯乙烯的反应导致形成了聚合物接枝的二氧化钒(V)络合物PS-im [VVO 2(pan)](4)。所有这些复合物的特征在于各种光谱技术(红外,电子,NMR(1 H和51 V)和电子顺磁共振(EPR),热场发射扫描电子显微照片(FE-
CF3CO2ZnEt-mediated highly regioselective rearrangement of bromohydrins to aldehydes
A highly efficient and selective rearrangement reaction of bromohydrins to aldehydes mediated by CF3CO2ZnEt was described. The secondary and tertiary aldehydes were prepared under mild conditions in good to excellent yields (85–99%). The scope and limitations of this rearrangement process were also investigated.

Pd salts catalyseoxidation of alcohols with CCl4 in the presence of K2CO3. Primary alcohols are oxidised to esters, and secondaryalcohols to ketones. CCl4 is converted to CHCl3. The reaction of allylicalcohols bearing a terminal olefinic bond with CCl4 or BrCCl3 in the presence of palladium catalyst at 110° affords 4,4,4-trichloro ketones. At 40°, simple adducts of CCl4 or BrCCl3 having a halohydrin
