(Hetero)adamantane Synthesis: A Triple Alkylation Reaction

Above: Examples of subtractive and additive mechanosynthesis under IM-STM/UHV conditions. HAT between activated 19 (chemisorbed on a Si(100)-2×1 surface) and H:Si(100)-2×1 SPC apex (A) and possible reaction outcomes between activated 19 (chemisorbed on a Si(100)-2×1 surface) and Si(100)-2×1 SPC apex including additive (C2-transfer) and subtractive (Si-atom abstraction) mechanosynthesis (B).
