Abstract:
Low-coordinate Cu-(I) ions play an important and varied role in organic synthesis, including the reduction of Michael acceptors and catalysis of azide-alkyne cycloadditions. The phosphaethynolate anion (i.e., PCO-) has similarly found a growing role as a P-atom transfer reagent. The convergence of these two topics, while rare, has been reported and has shown disparate results and reactivity. Herein, we report a pair of 2-coordinate Cu-(I) phosphaethynolate complexes and their capacity to deliver a P atom, generating PH-capped imidazoles.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
