Sodium hydride (NaH) is widely used as a Br?nsted base in chemical synthesis and reacts with various Br?nsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows NaH with unprecedented and unique hydride-donor chemical reactivity.
A One-Step Synthesis of 1-Halo-ω,ω-diphenylalkanes

Inverse addition of the anion derived from diphenylmethane to an excess of a 1,3- or 1,4-dihaloalkane at -78 deg C in THF provides a direct, one-step synthesis of 1-halo-ω,ω-diphenylalkanes.The chlorides can be prepared in 80-85percent purified yield while the bromides are available in yields of 60-65percent.
NOVEL REACTIONS WITH CARBON SUBOXIDE. IX. ANOMALOUS BEHAVIOUR OF C3O2 IN THE SYNTHESIS OF 1,4-BIS(p-NITROPHENYL)-1,2,3-BUTATRIENE

, p. 625 - 626 (2007/10/02)
The butatriene, 3, instead of pentatetraene, 4, has been obtained by an anomalous Wittig reaction of carbon suboxide, 1, with the ylide 2.
