Rhodium-catalyzed diarylation of oxalates using arylboron compounds
Dialkyl oxalates undergo selective diarylation on one of their carbonyl carbons upon treatment with arylboron reagents in the presence of a rhodium catalyst to give the corresponding α-hydroxydiarylacetates. Under similar conditions, the arylation of benzoylformate and benzil also proceeds efficiently.

Alkylating polymers: Resin-released carbenium ions as versatile reactive intermediates in polymer-assisted solution-phase synthesis
Solid-supported diazoalkane analogues for the smooth and clean esterifications of carboxylic acids [Eq. (1)] as well as of complex compound mixtures: the alkylating polymers presented here were synthesized as solid-supported 3-alkyl-l-aryltriazenes and ar
