环硼氮烷的研究进展 总被引:3,自引:0,他引:3
要对环硼氨烷的合成、结构和反应进行了综述。环硼氮烷可由氨或铵盐与氯化硼合成。经单晶X射线衍射分析证实其分子中存在共轭π键,其结构与苯相似,因而具有相似的物理性质,但因分子中硼和氮原子的电负性不同,它显示高度的反应活性,最典型的同氯化氢发生加成反应。环硼氮烷在化学中被称之“无机苯”。在应用基础研究中合成了氮化硼薄膜,它在替代有机物合成薄膜等材料中具有广泛的应用价值。 相似文献

1 INTRODUCTION
Catalytic hydrodechlorination is an elegant reaction for disposal of environmentally hazardous chlorocarbons,such as chloro-benzene[1].Development of a new catalyst with excellent stability is necessary due to the deactivation of supported noble metal catalysts[1].However the modification of catalytic properties of catalysts in hydrodechlorination reaction by introducing stable ligands to noble metals has been the least studied.Here the synthesis of Pd(Ⅱ) 2,9,16,23-symetrically tetrasubstituted phthalocyanines PdPTX4 (where X=-H,-NO2,-NH2 respectively) from phthalimide derivatives is reported,and their application as catalysts in hydrodechlorination of chlorobenzene,which is a representative environmentally hazardous materials is discussed. 相似文献

INTRODUCTION
Benzil is an important photosensitive initiator of organic synthesis intermediates, medicinal intermediates and ultraviolet solidified resin(UV resin), and is usually prepared by oxidizing benzoin. The oxidizers and methods reported are mainly: (PhCH2Et3N)+Br-/(PhCO)2O2/MeCN[1], DMSO/(COCl)2/CH2Cl2[2], CrO3*CH3NH2*HCl/Al2O3[3], the metallorganic compound[4], microwave radiation[5],etc. 相似文献
