“…4 The present work is aimed at studying the behavior of the antimony and bismuth Ph derivatives under the con ditions when both O and C phenylations of organic sub strates can occur simultaneously. For this purpose, we studied the interaction in the Ph 3 MX 2 -Cu(OAc) 2 -N a 2 P d C l 2 ( O A c ) 2 -H 2 C = C H C O 2 M e -M e O H (1 : 0.3 : 0.3 : 10 : 10) system at 50 °C in acetonitrile for 1 h. Triphenylbismuth(V) and triphenylantimony(V) dihalides (chloride, bromide) and dicarboxylates (acetate, propionate) were used as phenylating agents, because the difference in their properties in the reactions catalyzed by palladium and copper has been observed earlier.…”

The influence of the central metal atom and acid residue in a molecule of organometallic compound Ph 3 MX 2 (M = Bi, Sb; X = Cl, Br, OAc, O 2 CEt) on the direction and yield of dephenylation products in a methyl acrylate-methanol system in the presence of Cu(OAc) 2 and Na 2 PdCl 2 (OAc) 2 was studied at 50 °C in acetonitrile. The main product of dephenylation of the antimony compounds is methyl cinnamate (yield 0.31-1.59 moles per mole of the starting Ph 3 SbX 2 ), while anisole (0.55-0.97 mol) and halobenzene (0.67-1.04 mol) are those for compounds Ph 3 Bi(O 2 CR) 2 and Ph 3 BiHal 2 , respectively.

We have developed a method to study the photomechanism of our antimony carboxylate platform Ph 3 Sb(O 2 CR') 2 . A series of mechanistic studies followed the production of reaction byproducts by mass spectrometer, as they leave the film during exposure to EUV photons or 80 eV electrons. The major volatile products are CO 2 , benzene and phenol. The rate of outgassing is well-correlated with the reaction energy of decarboxylation of the carboxylate ligand as determined by density functional theory. Additionally, a deuterium labeling study was conducted to determine the source of hydrogen needed to convert phenyl and phenoxy to benzene and phenol. Specifically, EUV exposure of Ph 3 Sb(O 2 CCD 3 ) 2 creates d 0 -benzene and d 1 -phenol with >95% isotopic purity. Several mechanistic pathways are proposed and discussed.

Abstract. The cogeneration combined-cycle gas turbine plant with backpressure steam turbine is considered. A simple circuit of the plant increases its reliability, and the use of optimal temperatures of the heating and return water allows obtaining the highest thermal efficiency of the plant taking into account the ratio of its electric and heat power. The technical and economic efficiency of the combined-cycle plant with back-pressure steam turbine is studied to estimate the capital investment. The parameters and conditions to maximize the net present value growth relative to the base version are determined.
