The invention provides processes and materials for the efficient and costeffective functionalization of alkanes and heteroalkanes, comprising contacting the alkane or heteroalkane and a soft oxidizing electrophile comprising Se(VI) or Te(VI), in an acidic medium, optionally further comprising an aprotic medium, which can be carried out at a temperature of less than 300 C. Isolation of the alkylselenium or alkyltellurium intermediate allows the subsequent conversion to products not necessarily compatible with the initial reaction conditions, such as amines, stannanes, organosulfur compounds, acyls, halocarbons, and olefins.
