Compounds in which a carbon-hydrogen bond is adjacent to several carbon-metal bonds promise to be particularly good donors of hydrogen. The synthesis, structure, and redox reactions of one member of this group of compounds, tris [(triphenylstannyl) methyl] methane (2), are reported. Triphenylcarbenium is reduced to triphenylmethane less rapidly by stannane 2 than by bis [(triphenylstanny1) methyllmethane (1 1). The unexpectedly low ...
