Organic chemistry exercises

After 1828 the definition of organic chemistry (Exercise 13-1) was changed. How was it changed and what experiment required the change ...

Browse through The Journal of Organic Chemistry, Journal of the American Chemical Society, and Organic Letters. What variations in sectional divisions do you see Are all headings shown explicitly Repeat this exercise with two or three non-ACS chemistry journals (e.g., Applied Surface Science, Chemical Physics, and Journal of Chromatography A, all published by Elsevier). 

Find three synthesis articles in The Journal of Organic Chemistry. Compare the Methods sections in these articles with excerpts 3K and 3L. Which of your three articles, if any, include the same types of information that you reported in parts a, b, and c of exercise 3.14 ... 

In journals such as The Journal of Organic Chemistry and Organic Letters, equations are often included in tables, and the equation and table entries are linked by compound labels. Exercises 4.16 and 4.17 illustrate this convention. 

Find out if your set of rules for schemes (generated as part of exercise 5.9) applies to schemes in other articles. Check three articles in The Journal of Organic Chemistry or Organic Letters to see if your rules hold true. In these articles, how do the authors use compound labels and accompanying text to walk the readers through the schemes ...

Carbenoid reactions are, of course, of considerable synthetic utility in organic chemistry, but consideration of this aspect is beyond the scope of the present work. While reactions in solution will be the major preoccupation, evidence from investigations of carbenes in the gas phase and in the solid state will also be included, although due caution must be exercised in translating conclusions from one phase to another.

Commercial molecular model kits vary in style, size, material composition, and the color of the components. The set which works best in this exercise is the Molecular Model Set for Organic Chemistry available from Allyn and Bacon, Inc. (Newton, MA). Wood ball and stick models work as well. For 25 students, 25 of these sets should be provided. If you wish to make up your own kit, you would need the following for 25 students ... 

No other profession is endowed with such a rich landscape, draws inspiration from so many fields of science, exercises the hand and mind in so many different ways, offers such opportunities to employ creative instincts, and mixes ideas, theory, and experiment on a daily basis. Hurrah for the science of organic chemistry, and for the joy it brings those who play the research game. 

Conjugate addititxis to a,p-unsaturated carbene complexes have not been extensively studied however, from the few reports that have appeared in the literature one can get a brief sense of the scope, limitations and special features of these reactions that may ultimately find application in synthetic organic chemistry. One of the earliest examples involves the addition of amines to alkynyl carbene complexes. The example in Scheme 19 is particularly interesting because complete control between 1,4- versus 1,2-addition can be exercised simply by proper choice of reaction temperature. The complex (119) suffers exclusive 1,2-addition with dimethylamine at -90 °C and exclusive 1,4-addition at -20 C. The 1,2-adduct (120) will further react with dimethylamine, but the 1,4-adduct (122) will not. This example demonstrates the importance of being attentive to reaction conditions when preparing amino carbene complexes, such as the alkynyl complex (120), or the alkenyl complex (76) in Scheme 11.
