ISBN-10: 0080405932

ISBN-13: 9780080405933

Quantity 2 offers regularly with the addition reactions of delocalized carbanions (enolates) and their artificial family (metalloenamines, enol ethers, allyl organometallics) with carbonyl compounds, imines and iminium ions. significant emphasis is put on C-C bond-forming reactions comparable to the aldol and Mannich reactions. Acylation reactions also are integrated during this quantity. a number of subject matters that experience no longer formerly been reviewed are coated, together with using enzymatic aldol reactions in synthesis and the Passerini-Ugi reactions.

Sample text

Note that there is now only one lone pair of electrons. The second lone pair, which normally exists in the neutral molecule, is involved in the dative bond to the hydrogen cation. Write the equation that represents the further addition of another hydrogen cation to the hydroxonium ion. Draw a dot and cross structure for the resultant ion. Calculate the charge that is resident on each atom in this ion. For each of the four hydrogens the charge is again zero; while on the oxygen, it is plus two. There are eight electrons accommodated in the valence shell of the oxygen atom.

E. 6−8+ ½(6)=+1. Note that there is now only one lone pair of electrons. The second lone pair, which normally exists in the neutral molecule, is involved in the dative bond to the hydrogen cation. Write the equation that represents the further addition of another hydrogen cation to the hydroxonium ion. Draw a dot and cross structure for the resultant ion. Calculate the charge that is resident on each atom in this ion. For each of the four hydrogens the charge is again zero; while on the oxygen, it is plus two.

Now that you are fully familiar with the number of electrons that can be accommodated in the valence shell of the common elements when they are combined in neutral species, we may proceed to the next step, which is the counting of electrons in molecular species that carry a whole unit of charge and the determination of which atom has gained or lost an electron. 4 Molecules with whole charges This is the area in which most mistakes are made. Most mechanisms that will be examined in the second part of this book deal with intermediates that carry one or more whole charges.
