Condensation reactions of (chlorodifluoromethyl)benzene and (chlorodifluoromethoxy)benzene with phenoxide and thiophenoxide ions have been performed in DMF or NMP with heating. In these conditions, the reaction between phenylselenide ion and (chlorodifluoromethyl)benzene did not occur. This latter ...

SYNTHESIS AND REACTIONS OF YLIDIC THIABENZENES Synthesis and structure of novel ylidic thiabenzenes, 1-cyano-and benzoyl-2-methyl-2-thianaphthalenes (VI and X), are discussed. The reactions of VI with several electrophiles such as dimethyl acetylenedicarboxylate, methyl propiolate, d... M Hor...
Photochemical oxidative addition reactions of (η5-cyclopentadienyl)bis(ethene)rhodium with dihydrogen and trialkylsilanes: Formation and isolation of rhod... Photolysis of CpRh(C/sub 2/H/sub 4/)/sub 2/ (1; Cp = eta/sup 5/-C/sub 5/H/sub 5/) in benzene or toluene in the presence ...
Treatment of [W(NAr′)(OCMe2CF3)2]2 with 2-butyne yields [W(NAr′)(OCMe2CF3)2]2(μ-MeCCMe). Addition of 4 equiv of CH3CN to [W(NAr′)(OCMe2CF3)2]2 in benzene gives a mixture of two products, A and B, which have the empirical formula W(NAr′)(OCMe2CF3)2(CH3CN), ...
Thermal reaction of 1-benzoyl-2-methyl-3,4-dihydro-2-thianaphthalene ( 1) with acids or thiols in benzene afforded ring-opened products cleaving C 1-S bond. On the other hand, ring-expanded product was produced by the reaction of 1 with imides or phenols....
In this study, a series of OH-initiated oxidation experiments of trimethylbenzene (TMB, C9H12) including 1,2,4-TMB, 1,3,5-TMB, 1,2,3-TMB, and 1,2,4-(methyl-D3)-TMBs (C9H9D3) were investigated in an oxidation flow reactor (OFR), in the absence and presence of NOx. Products...
Kinetics of gas‐phase addition reactions of methyl radicals. I. Addition to ethylene, acetylene, and benzene The reactions have been studied by a mass-balance method involving the photolysis of small amounts of biacetyl in the presence of a large excess of isobuta... PM Holt,JA Kerr - 《...
The cross-coupling reaction of 1 with aryl triflates instead of aryl halides was also accomplished in the presence of tetrabutylammonium iodide (n-Bu(4)NI) as the additive under similar conditions. 展开 关键词: halogen compounds (benzene compounds ...
