Mechanism of rhodium-catalyzed carbene formation from diazo compounds.
[reaction: see text] A large and normal nitrogen-15 kinetic isotope effect of 1.035 +/- 0.003 provides direct support for the proposed mechanism for the rhodium-catalyzed carbene formation from diazo compounds, which involves the fast formation of a metal-diazo complex followed by rate-limiting extrusion of N2. The large magnitude of the KIE indicates extensive C-N bond fission in the transitio...

متن کاملHow nucleophilic are diazo compounds?
The kinetics of the reactions of benzhydryl cations with eight diazo compounds 1 a-g were investigated photometrically in dichloromethane. The nucleophilicity parameters N and slope parameters s of these diazo compounds were derived from the equation log k (20 degrees C)=s (E+N) and compared with the nucleophilicities of other pi systems (alkenes, arenes, silyl enol ethers, silyl ketene acetals...
متن کاملZinc-catalyzed synthesis of 2-alkenylfurans via cross-coupling of enynones and diazo compounds.
Inexpensive, less-toxic ZnCl2 serves as the catalyst for selective cross-coupling of enynones and diazo compounds, an unprecedented reaction pathway for zinc carbenoids. A cascade sequence comprising formal cyclization/cross-coupling leads to a variety of 2-alkenylfurans.
متن کاملRh(III)-Catalyzed, Highly Selectively Direct C–H Alkylation of Indoles with Diazo Compounds
Rh(III)-catalyzed regioselective alkylation of indoles with diazo compounds as a highly efficient and atom-economic protocol for the synthesis of alkyl substituted indoles has been developed. The reaction could proceed under mild conditions and afford a series of desired products in good to excellent yields.
