Carbonyl Compounds Enols and Enolate Ons. Unsaturated and Polycarbonyl Compounds
ome of the most useful reactions of carbonyl compounds involve carbonhydrogen bonds adjacent to the carbonyl group. Such reactions, which can be regarded as the backbone of much synthetic organic chemistry, usually result in the replacement of the hydrogen by some other atom or group, as in the I I I I sequence H-C-C=O -+ X-C-C=O. The important examples we I I will consider in this chapter are ...
متن کاملMichael-type reaction of ethyl bromodifluoroacetate with alpha,beta- unsaturated carbonyl compounds in the presence of copper powder.
We have reported that the reaction of ethyl bromodifluoroacetate (1) with alkenyl iodides in the presence of copper powder gives ethyl alkenyldifluoroacetates. As an extension of this reaction, reaction of 1 with Michael acceptors in the presence of copper powder was examined and found to give 1,4-addition products selectively, unless the acceptor has a group stabilizing a radical intermediate,...
متن کاملStabilization of the substrate reaction of horseradish peroxidase with o-phenylenediamine in the enzyme immunoassay.
When the horseradish peroxidase reaction is stopped with acid, the decay of unconverted hydrogen peroxide is responsible for the further oxidation of o-phenylenediamine. This leads to a time-dependent flattening of the standard curve in the enzyme immunoassay, after the reaction has been stopped. Addition of reducing agents, such as sulphite ions, to the stopping solution, prevents the further ...
متن کاملAgOTf-catalyzed one-pot reactions of 2-alkynylbenzaldoximes with α,β-unsaturated carbonyl compounds
AgOTf-catalyzed one-pot reactions of 2-alkynylbenzaldoximes with various α,β-unsaturated carbonyl compounds under mild conditions are described, which provides a facile and efficient pathway for the synthesis of 1-alkylated isoquinoline derivatives. The method tolerates a wide range of substrates and allows for the preparation of the products of interest in moderate to excellent yields.
متن کاملThe reaction of azide ions, N3, with metal carbonyl compounds; an electrospray mass spectrometry study
Monoand poly-nuclear metal carbonyls, and substituted analogues, have been analysed in the presence of N3 − ions by negative-ion electrospray mass spectrometry. Most complexes yield the appropriate isocyanate-containing anions by conversion of a CO ligand to an NCO one with elimination of N2. In some cases [M+N3] − ions are observed; for species such as H2Os3(CO)10 or Ru5C(CO)15 these arise fro...
