Radical-anions and dianions of methylphenylacetylene. The role of dianions in protonation and electron-transfer processes
Abstract
Kinetic and product studies show that electron transfer to methyl(phenyl)acetylene (MPA) gives its dianions (MPA2–,2Na+) which are protonated by MPA yielding PhCHMe,Na+ and Ph
C
CH2,Na+ as the products.
