Transition metal catalysis represents a relatively unexplored but potentially useful route to form bonds between main group elements. Previous work in the area of amine-borane adduct dehydrocoupling has exclusively employed late transition metal (e.g., Rh) catalysts which were found to predominantly operate via a heterogeneous mechanism. Herein, we present a new, early transition-metal-catalyze...
Organotins are a group of chemical compounds that have a tin atom covalently bound to one or more organic groups. The best-studied organotin is tributyltin chloride, which is an environmental pollutant and an endocrine disruptor. Tributyltin chloride has been shown to bind to PPARγ/RXRα and induces adipogenesis in different mammalian cells. However, there are few studies with other organotin co...
The article provides anatomic information about cervicothoracic ganglion in roe deer. For this purpose 12 cervicothoracic ganglia obtained from the right and left sides of 6 mature roe deer weighing 18-25 kg of both sexes were investigated. Cervicothoracic ganglion was located at the first intercostal space and ventrolateral side of longus colli muscle. This ganglion which was in various forms ...
2,4-Dichloro-, 4,6-dichloro-, 2,4,6-trichloroand tetrachloropyrimidine undergo nucleophilic displacements by 4-(dimethylamino)pyridine to give (pyrimidine-2,4-diyl)-1,1’-bis[4-(dimethylamino)pyridinium] dichloride, (pyrimidine-4,6-diyl)-1,1’-bis[4-(dimethylamino)-pyridinium] dichloride, (pyrimidine-2,4,6-triyl)-1,1’,1”-tris[4-(dimethylamino)pyridinium] trichloride, and (5chloropyrimidine-2,4,6-...
Mylohyoid and anterior belly of the digastric muscles are supplied by a branch from the inferior alveolar nerve called the mylohyoid branch. Here we present an unusual finding in a 60-year-old male cadaver in which the mylohyoid muscle is supplied by a branch from hypoglossal nerve in addition to its usual nerve supply. Hypoglossal nerve after giving superior root of the ansa cervicalis and mus...
The interaction of 3,3-bis(1-methylimidazol-2-yl)propionate (BIMP) with dimethyltin(IV) dichloride (DMT), dibutyltin(IV) dichloride (DBT), and diphenyltin(IV) dichloride (DPT) is investigated at 25°C and 0.1 M ionic strength in water for dimethyltin(IV), and in a 50% dioxane-water mixture for dibutyltin(IV) and diphenyltin(IV). The stepwise formation constants of the 1 : 1 and 1 : 2 complexes f...
