Copper(II) compounds catalyze the reaction of 1,1-diphenylethylene with diazoacetic acid ethylester. The main product is 2,2-diphenylcyclopropane carboxylic acid ethylester. The formation of the carbene dimerization products fumaric and maleic acid diethylester can be suppressed by the continuous ...

The action of diazoacetic ester on pyridone-2: A new synthesis of 2-pyridoxyacetic acidEthyl 2-pyridoxyacetate is obtained as chief product, together with a small amount of N-(2-pyridonyl) acetic ester, by reacting pyridone-2 with ethyl diazoacetate....
ChemInform Abstract: Synthesis and Carbenic Decomposition of Functionally Substituted Diazoacetic Acid Esters. Part 2. 2-Iodoethyl Diazoacetate.cyclopropane derivativesThe nucleophilic replacement of bromine in 2-bromoethyl diazoacetate (I) gives the corresponding iodoethyl ester (II) which produce the ...
of formula (II): N2CHCO-O-CH2CH2-X (II) (where X = a group removable as an anion such as Cl, Br, I, alkyl- or aryl-sulphonyloxy) is reacted with trimethylamine; or diazoacetic acid-2-dimethylaminoethyl esters (IV) are quaternised with a methylating agent. (I) may be used ...
The novel procedure for the Pd-catalyzed hydroarylation of alpha-diazoacetic ester is reported. In the presence of a catalytic amount of PdCl2(PPh3)(2) the three-component reaction of aryl iodides, ethyl diazoacetate, and formic acid proceeds smoothly resulting in the formation of a series of...
