Ketones state correlation diagram

Fig. 15 State correlation diagram for hydrogen abstraction by ketones. (Adapted from Salem, 1974)...

One example of interest is the hydrogen abstraction process by the triplet n-tt excited state of a ketone. The correlation diagram is shown in Fig. 11. 

Figure 6.24. State correlation diagram for the a cleavage of saturated ketones. The path to a bent acyl radical is shown on the right, that to a linear acyl radical to the left. The right-hand part of the diagram corresponds to the front face of the three-dimensional representation in Figure 6.23 the left-hand part corresponds to the cross section along the diagonal in Figure 6.23.

A classification of photochemical reactions built on the unifying concept of state correlation diagrams is proposed. Reviews include the photochemistry of organo-sulphur compounds, Py-unsaturated ketones,and cyclobutanones. ... 

The correlation diagram for hydrogen abstraction by a ketone has been derived in Example 4.5 (Section 4.2.3). From this diagram it can be concluded that no reaction is to be expected from the ( r,jr ) states for the in-plane... 

Reaction (69) takes place via the , singlet and triplet states of the ketone (Kellmann and Dubois, 1965). Using what are commonly termed Salem diagrams, Salem (1974) illustrated the manner in which the excited , state of the reactants correlates smoothly with the ground state products this is illustrated in Fig. 15. The surface crossing that is indicated is...
