Abstract
![]()
Appetite for reactions
involving PH3 has grown in the
past few years. This in part is due to the ability to generate PH3 cleanly and safely via digestion of cheap metal phosphides
with acids, thus avoiding pressurized cylinders and specialized equipment.
In this perspective we highlight current trends in forming new P–C/P–OC
bonds with PH3 and discuss the challenges involved with
selectivity and product separation encumbering these reactions. We
highlight the reactivity of PH3 with main group reagents,
building on the early pioneering work with transition metal complexes
and PH3. Additionally, we highlight the recent renewal
of interest in alkali metal sources of H2P– which are proving to be useful synthons for chemistry across the
periodic table. Such MPH2 sources are being used to generate
the desired products in a more controlled fashion and are allowing
access to unexplored phosphorus-containing species.
