摘要: Catalyst effectiveness for metal carbene formation and reactions has been surveyed using N-(tert-butyl)-3-[(tert-butyldimethylsilyl)oxy]-2-diazo-N-(4-chlorobenzyl)but-3-enamide in the of products from both intramolecular C–H insertion aromatic cycloaddition. Both are indicators intermediates, this system provides a means to assess catalysts formation. Donor–acceptor cyclopropene production reactant enoldiazoacetamide monitored its formation, independently formed also used Catalysts rhodium(II), copper(I), silver(I), Pd(II), cationic Au(I), Zn(II) convert donor–acceptor which serves as resting state intermediate carbene, derivative give same ratios cycloaddition products. copper(II) ruthenium(II...
