In this question, reasons for this observed trend of reactivity of different types of carbonyl compounds are discussed.

I would like to know where we can place $\alpha,\beta$ unsaturated carbonyls in this list.

Initially I thought we can place them above acyl chlorides because now we have 2 electrophilic carbons but then I think the reactivity of both of the carbons should also be reduced because of conjugation so they should be placed somewhere in the middle, but where exactly?

  • $\begingroup$ What carbonyls? Ketones? $\endgroup$ – Mithoron Jul 12 '18 at 19:00
  • $\begingroup$ Both aldehydes and ketones @Mithoron $\endgroup$ – Archer Jul 12 '18 at 19:09
  • $\begingroup$ Well, they are already there, as ketones and aldehydes. $\endgroup$ – Mithoron Jul 12 '18 at 19:30
  • $\begingroup$ @Mithoron Presence of adjacent unsaturation is going to affect reactivity, isn't it? $\endgroup$ – Archer Jul 12 '18 at 19:31
  • $\begingroup$ Everything does, but you seem to overestimate it. $\endgroup$ – Mithoron Jul 12 '18 at 19:40
