Phthalide synthesis through dehydrogenated lactonization of the C(sp3)-H bond by photoredox catalysis

A practical and efficient method is established for the direct oxidative lactonization of the C(sp3)-H bonds relying on visible-light-induced photoredox catalysis. This protocol expediently allows the delivery of diverse phthalides using oxygen as the sole terminal oxidant under metal-free conditions at room temperature. Notably, the choice of an appropriate hydrogen atom transfer (HAT) cocatalyst is revealed to be critical for the success of this process.

INVESTIGATION OF THE STRUCTURE OF 3,3-DIALKYL(ARYL)PHTHALIDES AND 3,3-DIALKYL(ARYL)THIOPHTHALIDES BY IR SPECTROSCOPY

In 3,3-dialkyl(aryl)phthalides and the corresponding thiophthalides the frequencies of the stretching vibrations of the carbonyl group correlate with the sum of the Taft ?* induction constants of the substituent at C3 of the heterocycle.The substitution of oxygen in the ring by sulfur substantially reduces the frequency of the carbonyl stretching vibrations.
