The frustrated Lewis pair (FLP) derived from 2,6-lutidine and B(C6 F5 )3 is shown to mediate the catalytic hydrogenation of CO2 using H2 as the reductant and a silylhalide as an oxophile. The nature of the products can be controlled with the judiciou

Reactions of benzyl potassium species with CO are shown to proceed via transient carbene-like intermediates that can undergo either dimerization or further CO propagation. In a sterically unhindered case, formal dimerization of the carbene is the dom

We describe the synthesis of N-functionalised phosphinecarboxamides obtained by reaction of the 2-phosphaethynolate anion (PCO-) with diamines, specifically hydrazine, methylenediamine and ethylenediamine, in the presence of acid. The resulting neutr

Frustrated Lewis pairs (FLPs) are well known for their ability to activate small molecules. Recent reports of radical formation within such systems indicate single‐electron transfer (SET) could play an important role in their chemistry. Herein, we

Archetypal phosphine/borane frustrated Lewis pairs (FLPs) are famed for their ability to activate small molecules. The mechanism is generally believed to involve two‐electron processes. However, the detection of radical intermediates indicates that

The reaction of the intramolecular frustrated Lewis pair (FLP) tBu2PCH2BPh2 with the amine-boranes NH3 center dot BH3 and Me2NH center dot BH3 leads to the formation of the corresponding FLP-H2 adducts as well as novel five-membered heterocycles that

Reactions of Ph3GePCO with KP(t-Bu)2 and Ph3SiCl, or direct reaction with Ph3SiP(t-Bu)2 provides the (Z)- and (E)-isomers of the phosphaalkene (t-Bu2)PC(OSiPh3)P(GePh3) 2, respectively. These isomers interconvert thermally and photochemically, while

P-yramids: Tetrahedranes are highly strained molecules, and the all-carbon (CtBu)4 and all-phosphorus species P4 have been known for decades and centuries, respectively. Despite this, the mixed P/C tetrahedranes were unknown until recently when the s

The phosphaketene Ph3 GePCO is shown to react with the phosphide KP(tBu)2 to generate the anion [Ph3 GePC(O)P(tBu)2 ]- 1. This species reacts with CH3 I or ClGePh3 to give the dissymmetric diphospha-ureas (tBu)2 PC(O)P(GePh3 )(CH3 ) 2 and (Ph3 Ge)2 P
