Isotope Effects and the Mechanism of Photoredox-Promoted [2 + 2] Cycloadditions of Enones

13C kinetic isotope effects (KIEs) for the photoredox-promoted [2 + 2] cycloaddition of enones were determined in homocoupling and heterocoupling examples. The only significant KIEs were observed at the β carbon, indicating that Cβ-Cβ bond formation is irreversible. However, these KIEs were much lower than computational predictions, suggesting that product selectivity is determined in part by a step prior to Cβ-Cβ bond formation. The results are explained as arising from a competition between C-C bond formation and electron exchange between substrate alkenes. This idea is supported by a relatively small substituent effect on substrate selectivity. The possible rates for electron transfer and bond-forming steps are analyzed, and the competition appears plausible, particularly if the mechanism involves a complex between reduced and neutral enone molecules.

Synthetic Applications of the 1-Cyclobutenyltriphenylphosphonium Salt. Synthesis and Reactions of 1,2-Difunctionalized Cyclobutanes

Symmetrical and unsymmetrical 1,2-bis(ylidene)cyclobutanes 6a-g and 6h were synthesized in good or moderate yields by the double Wittig reaction of a triphenylphosphonium ylide with aldehydes.The 1,2-bis(ylidene)cyclobuta

Studies on Organic Fluorine Compounds. XXXI. Oxidative Coupling of Ketone Enolates and Trimethylsilyl Enol Ethers by Means of Cu(OTf)2

The oxidative coupling of ketone enolates and trimethylsilyl enol ethers by means of cupric trifluoromethanesulfonate is described in detail. 1,4-Diketones were effectively prepared by treating lithium enolates with Cu(OTf)2 in i-PrCN. 1,3-Cyclopentanedione derivatives were synthesized through intramolecular coupling of 2,4-pentanedione derivatives.Treatment of trimethylsilyl enol ethers with Cu(OTf)2 in i-PrCN also afforded the corresponding coupling products.
