Type 17 Lewis Acid/Base Complexation Chemistry

Reduction of the Organic π-System
Bonding: π-System Lewis Acids form complexes with hydride ions which exist as C-H bonds.
Charge: Complexes may be negatively charged or they may be neutral.

π-System Lewis acids are reduced by s-HOMO Lewis bases:

Hydride ion donor reagents, such as lithium aluminium hydride or sodium borohydride, both Type 6 complexes:

H2 plus transition metal catalyst:

During such reductions the hydrogen is likely to be in the form of a transition metal/hydride Type 21 complex.

The saline hydride reagents, NaH etc., Type 5 complexes, are generally too Brønsted basic to be used as organic reducing agents.

Congeneric Series: Few series or planars of interest.
