Cycloaddition reactions of unsaturated sulfones
The reaction of a series of allyl-substituted bis(phenylsulfony1)methanes or dimethyl malonates with 2,3-bis(phenylsulfonyl)l13-butadiene in the presence of base afforded alkenyl-substituted allenes in good yield. The reaction proceeds by initial attack of the soft carbanion onto the terminal position of the diene and subsequent PhS02elimination to give the phenylsulfonyl substituted allene. Th...
متن کاملComputational study of cycloaddition reactions
Cycloaddition reactions between 1,3-butadiene and the C-terminated SiC(1 0 0)-c(2 · 2) surface have been addressed using quantum-chemical methods. The c(2 · 2) structure consists of ACBCA bridges between underlayer Si atoms which themselves form SiASi bonds. Of various possible reaction products, the one formed by a [2+ 4] reaction with the ACBCA bridge (giving a species resembling 1,4-cyclohex...
متن کاملTheoretical studies on cycloaddition reactions
Cycloaddition reactions represent one of the most powerful processes in organic chemistry. The most common types of cycloaddition reactions are the Diels-Alder (DA) and the 1,3-dipolar cycloaddition reactions (1,3-DCs) which lead to five and six membered rings, respectively. In our ongoing efforts to contribute to the understanding of DA and 1,3-DCs; we studied the following using the B3LYP/6-3...
متن کاملReactions of cyclopentadienyl-amidinate titanium imido compounds with CO2: cycloaddition-extrusion vs. cycloaddition-insertion.
A combined experimental and DFT study of the reactions of cyclopentadienyl-amidinate titanium imido complexes with CO(2) is reported. Cycloaddition reactions of the aryl imido compounds Ti(eta-C(5)R(4)Me)(NAr){R(2)C(NR(1))(2)} (R = H or Me; R(1), R(2) = SiMe(3), Ph or (i)Pr, Me) with CO(2) gave the corresponding N,O-bound carbamate complexes Ti(eta-C(5)R(4)Me){N(Ar)C(O)O}{R(2)C(NR(1))(2)}. Thes...
متن کاملCycloaddition reactions of (C6F5)2BN3 with dialkyl acetylenedicarboxylates.
The 1,3-dipolar cycloaddition reactions of the electron deficient boron azide, (C6F5)2BN3 (1) with the electron-poor acetylenes RO2CC≡CCO2R (R = Me, Et) afforded the new mono- and bis-1,2,3-triazole derivatives and .
