The use of titanium(IV) chloride as a Lewis acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. The route is regioselective, leading to ortho C-acylated products in satisfactory to high yields in most cases.
A series of novel photochromic spiropyrans are disclosed in which a spiro-adamantane group is introduced into the 2-position of the benzopyran or naphthopyran ring. The spiropyran compounds of the invention exhibit heliochromic properties, i.e. they color in sunlight and fade rapidly at ambient temperatures in the absence of U.V. light, making them good candidates for use in the manufacture of sunglasses. The invention includes lenses which darken in sunlight and incorporate the novel spiropyrans and a process for the preparation of the spiropyran compounds.
Bismuth triflate was found to be an efficient catalyst in the Fries rearrangement of phenyl or 1-naphthyl acetates. Both reactions proceeded smoothly with a catalytic amount of bismuth triflate (10 mol%) to afford the corresponding hydroxyaryl ketone in moderate to good yields in most cases.
Synthesis, characterization and biological relevance of Ni(II) and Fe(III) complexes of the halogenated 2,2′-((pentane-1,3-diylbis(azanylylidene))bis(ethan-1-yl-1-ylidene))bis(naphthalen-1-ol) schiff base ligand

that Ni(II) complexes are diamagnetic and Fe(III) complexescontain five unpaired electrons. To evaluate the antibacterial activity of newly synthesized Schiff baseligands and their metal complexes were screened by using two Gram-positive and two Gram-negative bacterial strains. It was found that; the newly synthesized metal complexes were more potent compared to the Schiff baseligands. Furthermore
在此,我们报告了四种新型 Ni(II) 和 Fe(III) 席夫碱配合物的合成、表征和生物学特性。这些配合物已通过使用紫外可见光、FT-IR、1 H 和13 C NMR、LCMS、TGA-DTA、ESR 和粉末 X 射线衍射进行表征。IR结果证实配体的四齿结合涉及两个萘酚氧和两个偶氮甲碱氮。1 H NMR和13个C NMR的光谱数据(H 2L2) 及其金属配合物与提出的结构非常吻合。Ni(II) 和 Fe(III) 配合物的热重研究表明存在配位的水分子,最终产物是金属氧化物的形成。从粉末X射线衍射数据,我们证实Ni(II)配合物排列在三斜晶系中,而Fe(III)配合物排列在空间群为P1的单斜晶系中。ESR 线显示 Ni(II) 配合物是抗磁性的,而 Fe(III) 配合物包含五个不成对的电子。为了评估新合成的席夫碱配体的抗菌活性,通过使用两种革兰氏阳性和两种革兰氏阴性细菌菌株筛选了它们的金
