An Alkali Amide Approach to Triphosphabenzenes
1 Introduction Incorporating phosphorus atoms into aromatic systems can impart unique and desirable properties applicable to materials science, coordination chemistry, and small molecule activation. Consequently, there have been several detailed studies to establish effective synthetic routes to phosphorus heterocycles, including phosphabenzenes [1-6].

Amine-Boranes as Transfer Hydrogenation and Hydrogenation Reagents: A Mechanistic Perspective
Abstract Transfer hydrogenation (TH) has historically been dominated by Meerwein–Ponndorf–Verley (MPV) reactions. However, with growing interest in amine–boranes, not least ammonia–borane (H3N⋅BH3), as potential hydrogen storage materials, these compounds have also started to emerge as an alternative reagent in TH reactions. In this Review we discuss TH chemistry using H3N⋅BH3 and their analogues (amine–boranes and metal amidoboranes) as sacrificial hydrogen donors.
1,1-Diphosphines and divinylphosphines via base catalyzed hydrophosphination
A catalytic hydrophosphination route to 1,1-diphosphines is yet to be reported: these narrow bite angle pro-ligands have been used to great effect as ligands in homogeneous catalysis. We herein demonstrate that terminal alkynes readily undergo double hydrophosphination with HPPh2 and catalytic potassium hexamethyldisilazane (KHMDS) to generate 1,1-diphosphines. A change to H2PPh leads to the formation of P,P-divinyl phosphines.
β-Diketiminate complexes of the first row transition metals: Applications in catalysis
Although ?-diketiminate complexes have been widely explored in stoichiometric studies, their use as catalysts is largely underdeveloped.
