- The
pinacol–pinacolone
rearrangement is a
method for
converting a 1,2-diol to a
carbonyl compound in
organic chemistry. The 1,2-rearrangement
takes place...

pinacol is
notable for
undergoing the
pinacol rearrangement in the
presence of acid and for
being the
namesake of the
pinacol coupling reaction...
- A
pinacol coupling reaction is an
organic reaction in
which a carbon–carbon bond is
formed between the
carbonyl groups of an
aldehyde or a
ketone in presence...

atoms and two
pinacolato ligands. It has the
formula [(CH3)4C2O2B]2; the
