“…There are significant parallels between this maingroup-mediated chemistry and transition-metal catalysis including the type and scope of P-P bond formation as well as strong implications for mechanistic similarities in some cases. The interconnection between the main-group and transition-metal chemistries was described in some detail by Wright and coworkers [83].…”

This updated version of a 2008 review presents work in the still developing field of dehydrogenative coupling reactions of phosphines. Catalytic phosphorus-element bond formation via dehydrocoupling has rapidly expanded since the first discoveries in the mid 1990s. A survey of the available catalysts, P-P and P-E products, and mechanistic understanding is presented with emphasis on the emerging synthetic applications of this reaction.

“…Moreover, these reactions are considerably faster than transition-metal counterparts. Thus, the only major limitation in this chemistry is the need for stoichiometric main-group reagents [83].…”

“…In these isomers, all phosphorus atoms are tri-coordinated, forming one bond to the other phosphorus atom and two bonds each to two distinct lithium atoms. While the precise mechanisms involved in P-P bond formation are an active area of research, [36][37][38] many such diphosphorus compounds are, or have the potential to be, involved in reactions of great chemical importance. For example, compounds with P-P linkages are often precursors involved in the formation of many organic compounds, 39 such as in the formation of phosphonium salts (i.e., phosphonium ylides used as Wittig reagents) 40 and diphosphines (i.e., metal chelating agents, such as Ph 2 PCH 2 PPh 2 ).…”

Stability and bonding of new superalkali phosphide species

New superalkali phosphide species with the molecular formulas F2Li3P, F2Li3P2, and F4Li6P were investigated. Using the CBS-QB3 composite method to optimize geometry and energetic parameters, four monophosphides, two diphosphides, and one disuperalkali phosphide were discovered that contain intriguing structural features, including hyperlithiation, phosphorus-phosphorus bonds, and planar tetracoordinated phosphorus. It is believed that these features lend to the stability of these structures and may warrant further experimental investigation of these phosphide species to determine if they could play some role in the development of novel chemical reactions and/or materials.

“…This type of main group dehydrocoupling reaction can be seen to be driven thermodynamically by the strength of the P-P single bond, which has the highest homoatomic bond energy between of any of the group 15 elements (ca. 201 kJ mol À1 ) [5]. The phosphorus counterparts [( t BuP) 4 P] À have been obtained by the in situ reactions of t BuPCl 2 and PCl 3 with Na metal in THF (Scheme 2) [6].…”
