negative effect on product formation (Table1, entries 6 and 7). The increase or decrease of the reaction current slightly reduced the product yield (Table1, entries 8 and 9). While a lower ethyl diazoacetate of 1.5 mmol or a lower amount of methanol showed a decrease in the amount of ...
It has been established that the formation of C 2-hydrocarbons over CaO-CaCl 2 catalysts involves the participation of atomic chlorine generated by the catalyst surface. It has been suggested that the reaction over Na/CaO and Li/CaO catalysts is initiated by atomic oxygen. The reactions schemes...

Oxidative dimerization of methane has been examined on CaO modified by chlorides or alkaline metals. It has been established that the formation of C 2-hydrocarbons over CaO-CaCl 2 catalysts involves the participation of atomic chlorine generated by the catalyst surface. It has been suggested that ...
Chemical halogenation is an important transformation in organic synthesis. Halogenations involve the use of reactive and toxic halogens (X2) or hydrogen halides (HX). Chemical halogenations are fast and exothermic, but with little regio- or stereoselecti
The oxidative addition reactions of the four-coordinated species Ru(NO)CI(AsPh,h (I) with acyl chlorides (RCOCI, R =C6H 5, CH,), alkyl and aryl halide, gaseous oxygen, and chlorine, bromine and iodine have been studied. The final products of these reactions are characterised on the bas...

Doping of alkaline and rare earth metals to A-site of the perovskite does not directly react during the reaction, but affecting the amount of lattice oxygen for oxygen migration ability [20]. Ishihara et al. [21] found that the electrical conductivity increased monotonically with an increasing ...
