DIBAL-H

DIBAL-H ((i-Bu)₂AlH) - reducing reagent. Partial reduction of esters to aldehydes. Common uses: Ester → Aldehyde (at -78°C), Nitrile → Aldehyde (via imine). Temperature critical! At -78°C stops at aldehyde. Warmer or excess gives alcohol.

Lindlar Catalyst

Lindlar Catalyst (Pd/CaCO₃/Pb) - reducing reagent. Partial reduction of alkynes to cis-alkenes. Common uses: Alkyne → cis-Alkene (stops at alkene). Poisoned catalyst - lead prevents over-reduction. Syn addition gives cis product.
