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. | Chemistry: | 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. |
