Mn(III)-based C-C bond formation: regioselective alpha '-allylation of various alpha,beta-unsaturated, alpha and beta-alkoxy alpha,beta-unsaturated ketones
Tanyeli, Cihangir (Elsevier BV, 2005-08-22)
The Manganese(III) -based regioselective alpha'-keto radical generation of unsaturated ketones is a versatile synthetic procedure with broad applicability. The generated alpha'-keto radical slowly creates a metal enolate in a solvent at reflux. The resultant metal enolate affords the corresponding alpha'-allylated alpha,beta-unsaturated ketones in good yields. This method is the first example of the metal mediated regioselective alpha'-allylation of alpha,beta-unsaturated ketones. The ketones that have alph...
Mn(III)-mediated radical C-C bond formation: Regioselective α′-allylation of α,β-unsaturated ketones
Tanyeli, Cihangir (2002-05-27)
Mn(OAc)(3)-mediated regioselective alpha'-allylation of alpha,beta-unsaturated enones is described. alpha'-Allyl alpha,beta-unsaturated enones are obtained through a radical process in good yields.
Mn-Cu and Mn-Cu-V mixed-oxide regenerable sorbents for hot gas desulfurization
Karayilan, D; Doğu, Timur; Yasyerli, S; Dogu, G (American Chemical Society (ACS), 2005-07-06)
Porous Mn-Cu and Mn-Cu-V mixed-oxide sorbents prepared by the complexation technique were tested for high-temperature removal of H2S in the presence of hydrogen gas. Sorption experiments carried out at 627 T in a fixed-bed reactor showed higher reactivity and also higher sulfur retention capacity (over 0.15 g of S/g of sorbent) for the Mn-Cu mixed oxide than for the Mn-Cu-V mixed oxide. Successive sulfidation-regeneration cycles demonstrated that the MnCu mixed oxide was also more stable than Mn-Cu-V, maint...
Mn(OAc)(3)-promoted sulfur-directed addition of an active methylene compound to alkenes
DELIOMEROGLU, Murat K.; Dengiz, Çağatay; CALISKAN, Rasit; BALCI, METİN (2012-07-22)
Various alkenes substituted at the 1,2-positions by phenyl, thiophene and furan rings were reacted with 3-(4-methoxyphenyl)-3-oxopropanenitrile in the presence of Mn(OAc)(3)center dot 2H(2)O. The exact structure and configuration of the dihydrofuran derivatives formed were determined. In all cases only one regioisomer was formed. The observed regioselectivity was explained on the basis of the formation of a complex between Mn(OAc)(3), alkene, and 3-(4-methoxyphenyl)-3-oxopropanenitrile, which directs the mo...
Mn(OAc)3 promoted addition of an active methylene compound to alkenes: mechanistic studies
Ceyhan, Selin; Balcı, Metin; Department of Chemistry (2015)
Radical cyclization of alkenes is one of the most important methods for the synthesis of cyclic compounds. The one electron oxidant Mn(OAc)3 has been used for many years for the oxidative addition of acetic acid to alkenes to give lactones. In this thesis, various alkenes substituted at 1,2-positions by phenyl and thiophene rings were reacted with active methylene compounds in the presence of Mn(OAc)3∙2H2O. The regioselectivity of the addition were searched. The mechanism for the addition was studied in con...
