Abstract The keto-enol tautomerism of 3-(2-hydroxy-4,4-dimethyl-6-oxo-cyclohexen-1-yl)isobenzofuran-1(3H-one (1), 3-(2-hydroxy-6-oxocyclohex-1-enyl)isobenzofuran-1(3H)-one (2), 3-(2-hydroxy-4-methyl-6-oxocyclohex-1-enyl)isobenzofuran-1(3H)-one (3), 3-(2-hydroxy-5-oxocyclopent-1-enyl)isobenzofuran-1(3H)-one (4) and 2-(3-oxo-1,3-dihydroisobenzofuran-1-yl)-1H-indene-1,3(2H)-dione (5) were investigated
A novel reaction pathway involving 1,3-diketones and 2,2′-dithiodibenzoylchloride that gives access to benzothiophenes with spiroketal, lactone, carbonyl, hydroxyl and carboxylic acid functionalities is discussed.

Man up your magnesium! By employing a MgCl2/Et3N system, aryl diketones can be generated from the Pd‐catalyzed carbonylative α‐arylation of acetylacetone with aryl bromides (see scheme). The method is ideal for the introduction of carbon isotopes into more complex structures, since only stoichiometric amounts of carbon monoxide are employed.
举起你的镁!通过使用MgCl 2 / Et 3 N系统,可以从Pd催化的乙酰丙酮与芳基溴的羰基化α-芳基化反应生成芳基二酮(请参见方案)。该方法非常适合将碳同位素引入更复杂的结构中,因为仅使用化学计量的一氧化碳。
