wherein A1, A2, A3, D, T, R4, R10, R11, R12 and k are as defined for formula (I) under (1), W1 is O, NR5 or S and R5 is as defined for formula (I) under (1), is reacted with a compound of formula wherein A3, R1, R2, R3, Q and m are as defined for formula...
HSALIMP reacts with nickel(II) bromide to form a mononuclear complex [Ni(HSALIMP)2Br2] (VIII), in which one metal ion combines with two neutral HSALIMP ligands. However HSALIEP, a similar ligand with one additional carbon atom in the chain, acts as a tridentate ligand (NNO), with ...
The invention discloses a method for preparing phenol, comprising the following steps: benzene and simple substance bromine generate bromobenzene and HBr under the action of catalyst, HBr reacts with metallic oxide MXO to generate metallic bromide MXBr2 and water; the generated bromobenzene reacts ...
However, phenol oxidation was not affected by the presence of Br~, even though Br~ reacts faster with sulfate radicals than phenol and was present in excess. This indicated that formed reactive bromine species such as Br' and Br2~-oxidize phenol under reformation of bromide. Formation of ...
The title compound, C12H15Br2N3O, is a hydrazone in which 3,5-dibromo-2-hydroxybenzaldehyde has reacted with 1-amino-4-methylpiperazine to form a product containing a C=N double bond. The piperazine ring adopts a chair conformation. The dihedral angle between the benzene ring and the C=N...
To introduce these initiators, C−H bond activation was performed by reacting [(ONOO)tBuY(X)(thf)] (X = CH2TMS, thf = tetrahydrofuran) with tert-butyl-dimethyl-silyl-functionalized α-methylpyridine to obtain the complex [(ONOOtBuY(X)(thf)] (X = 4-(4 -(((tert-butyldimethylsilyl)...
