Abstract

Upon UV irradiation in methanol, some l, l, l-triarylalkanes underwent an cu, a-elimination of two aryl groups to give biaryls and the corresponding carbene intermediates, which inserted into the OH bond of the methanol to afford methyl ethers and/or underwent a 1, 2-H shift to afford olefins. Furthermore, the efficiency of this elimination was highly dependent upon the bulkiness of the alkyl groups.
