Domino reactions of 2-methyl chromones containing an electron withdrawing group with chromone-fused dienes.
Domino reactions of 2-methyl substituted chromones containing an electron withdrawing group at the 3-position with chromone-fused dienes synthesized a diverse range of benzo[a]xanthones and complicated chromone derivatives. These multiple-step reactions result in either two or three new C-C bonds without a transition metal catalyst or an inert atmosphere.
متن کاملEthylene oligomerisation and polymerisation with nickel phosphanylenolates bearing electron-withdrawing substituents: Structure-reactivity relationships.
Three SHOP-type catalysts, in which the C=C(O) double bond was substituted by electron-withdrawing substituents, [Ni{Ph2PC(R1)=C(R2)O}Ph(PPh3)] (2: R1,R2 = -C(Me)=NN(Ph)-; 3: R1 = CO2Et, R2 = Ph; 4: R1 = CO2Et, R2 = CF3), were assessed as ethylene-oligomerisation and -polymerisation catalysts and compared to Keim's complex, [Ni{Ph2PCH=C(Ph)O}Ph(PPh3)] (1). A rationale for the influence of the d...
متن کاملThe Diels-Alder Cycloaddition Reaction of Substituted Hemifullerenes with 1,3-Butadiene: Effect of Electron-Donating and Electron-Withdrawing Substituents.
The Diels-Alder (DA) reaction provides an attractive route to increase the number of six member rings in substituted Polycyclic Aromatic Hydrocarbons (PAHs). The density functional theory (DFT) B3LYP method has been used in this work to inquire if the substitution of H over the edge of triindenetriphenylene (pristine hemifullerene 1) and pentacyclopentacorannulene (pristine hemifullerene 2), co...
متن کاملMass Spectrometric Observation of Electron and Proton Transfer Reactions between Positive Ions and Neutral Molecules*
T h e method of CERMAK and HERMAN has been appl ied to mass spectrometr ic studies of symmetrical electron and proton transfer processes. The characteristics of the ion source used have been investigated both experimental ly and theoretical ly. A new type of ionization ef f ic iency curve is obtained if the current of a secondary ion is plotted as a funct ion of the voltage between ionization c...
متن کاملMass Spectrometric Observation of Electron and Proton Transfer Reactions between Positive Ions
1. Die Leitfähigkeit der inneren Kornoberfläche ist sicherlich nicht schlechter als die des kompakten Materials; 2. die Austrittsarbeit zeigt ein ähnliches Verhalten wie die Leitfähigkeit beim Tempervorgang; 3. die Austrittsarbeit wird durch eine Chlordotierung erniedrigt; neuerdings fanden wir auch, daß sie durch eine Tl-Dotierung erhöht wird; 4. es gelang, einen quantitativen Zusammenhang zwi...
