A solution to the classic unsolved problem of olefin hydromethylation is presented. This highly chemoselective method can tolerate labile and reactive chemical functionalities and uses a simple set of reagents. An array of olefins, including mono-, di-, and trisubstituted olefins, are all smoothly hydromethylated. This mild protocol can be used to simplify the synthesis of a specific target or to directly "edit" complex natural products and other advanced materials. The method is also amenable to the simple installation of radioactive and stable labeled methyl groups.

The catalytic tritiation of rotenone results in the preparation of two products, the expected tritiated 6',7'-dihydrorotenone ([3H]DHR) and tritiated 6',7'-dihydrorotenol ([3H]DHR-ol). The ratio of [3H]DHR to [3H]DHR-ol is 9 to 1. Reversed-phase HPLC provided the purified [3H]DHR and [3H]DHR-ol with estimated specific activities of 45 and 60 Ci/mmol, respectively.
