A nitrido salt reagent of titanium.
Deprotonation of the parent titanium imido ((tBu)nacnac)Ti≡NH(Ntolyl2) ((tBu)nacnac(-) = [ArNC(t)Bu]2CH; Ar = 2,6-(i)Pr2C6H3) with KCH2Ph forms a rare example of a molecular titanium nitride as a dimer, {[K][((tBu)nacnac)Ti≡N(Ntolyl2)]}2. From the parent imido or nitride salt, the corresponding aluminylimido-etherate adduct, ((tBu)nacnac)Ti≡N[AlMe2(OEt2)](Ntolyl2), can be isolated and structura...
متن کاملInteractions of cationic bile salt derivatives with the ileal bile salt transport system.
Previous structure-activity studies of the active ileal bile salt transport system have demonstrated that a single negative charge on the side chain is essential for active transport. Furthermore, mutual inhibition studies between different pairs of bile salt substrates indicated that dihydroxy bile salts had a greater apparent affinity for the transport system than the trihydroxylated compound...
متن کاملCopper(II)-salt-promoted oxidative ring-opening reactions of bicyclic cyclopropanol derivatives via radical pathways
Copper(II)-salt-promoted oxidative ring-opening reactions of bicyclic cyclopropanol derivatives were investigated. The regioselectivities of these processes were found to be influenced by the structure of cyclopropanols as well as the counter anion of the copper(II) salts. A mechanism involving rearrangement reactions of radical intermediates and their competitive trapping by copper ions is pro...
متن کاملEvaluation of direct immunofluorescense on salt split skin in the differentiation of subepidermal autoimmune Bullous dermatoses
Background: Bullous pemphigoid (BP) is the prototype of subepidermal autoimmune bullous dermatoses (SABDs). Direct immunofluorescence on salt split skin substrate (DIF-SS) is one of the methods used to differentiate this group of dermatoses. Objective: We conducted this study in order to delineate the results of DIF-SS in SABD patients. Patients and Methods: Seventeen patients with a BP-like cl...
متن کاملSPECTROPHOTOMETRIC DETERMI NATION OF OSMIUM (VIII) WITH 1-HYDROXY 2- PYRIDINE - THIONE (SODIUM SALT) AS A REAGENT
A spectrophotometric study of osmium (VIII) complex of 1-hydroxy 2- pyridine thione (HPT) is presented. A red-violet complex, 0 s (HPT) is formed in a highly acidic solution, and shows maximum absorbance at 500 nm with molar absorptivity of 5.12 x 101. mol . cm . Beer's law is obeyed in the range of 3-60 ppm. Sandel's sensitivity of the method is 0.37 ?g.cm per0.001 ab sorbance unit. V (V)...
