چکیده
Abstract We have developed a nickel-catalyzed insertion reaction of an alkyne into 2-(trifluoromethyl)-1,3-benzothiazole to give seven-membered benzothiazepine that is converted 2-(trifluoromethyl)quinoline by thermal desulfidation. This process can be considered formal substitution sulfur atom with alkyne. The structure the thianickelacycle intermediate formed through oxidative addition C–S bond in benzothiazole nickel(0) was confirmed X-ray single-crystal analysis and situ absorption fine-structure spectroscopy.

Nickel-catalyzed intermolecular alkyne insertion into cyclobutanones.
Cyclobutanones reacted with alkynes in the presence of nickel(0) catalysts to produce cyclohexenones. Oxidative cyclization of the carbonyl group of the cyclobutanone and the alkyne with the nickel(0) was followed by beta-carbon elimination from the resulting oxanickelacyclopentene and subsequent reductive elimination. This reaction achieves a formal alkyne insertion between the carbonyl carbon...

the aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame
رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
