An active or functional organic compound is solubilized in a diaryl organic compound having a polar or polarizable functional group therein, as a solvent, cosolvent or additive, to form a composition thereof. Representative active or functional organic compounds include those present in personal care products, e.g., sunscreens containing UVA/UVB absorbing compounds, such as avobenzone, benzophenone-3, and 4-methylbenzylidene camphor. Such compositions also show increased SPF, UVA/UVB absorbance ratio, and critical wavelength performance properties.
dehydroxymethylative functionalization reaction of aliphatic alcohols under mild and catalyst-free conditions, representing a new paradigm for forging various C(sp3)–heteroatom bonds between diverse alkanols and N- or O-centered nucleophiles. In addition, detailed mechanistic investigations have been carried out, revealing that these reactions proceed through a β-scission/anodic oxidation/nucleophilic

An efficient metal free protocol has been developed for the synthesis of benzylic esters via a cross dehydrogenative coupling (CDC) involving alkylbenzene(s) as a self- or as a cross-coupling partner(s) via the intermediacy of Ar–COOH and the benzylic carbocation obtained from the other half of the alkylbenzene; both symmetrical as well as unsymmetrical esters can be prepared using Bu4NI and TBHP.
