Cyclic complex 2 with bridging carbonyl ligands was synthesized from a facile and reversible intermolecular carbonyl-borylene ligand coupling reaction at room temperature. Complex 2 exhibits an unprecedented coordination mode for boron-metal complexes, which is also reflected in its remarkable 11B NMR chemical shift of -57.2 ppm. Findings from spectroscopic, X-ray, and computational studies are presented, along with a proposed mechanism. Copyright
Fragmentation of an n-substituted one-coordinate phosphorus (Phosphaalkyne): Plausible generation of monovalent phosphorus species

A new one-step synthesis of a stable nitrogen-substituted phosphaalkyne (5) was developed, by the condensation of CsF (2), tris(trimethylsilyl)phosphine (3), and supermesityl isocyanate (4). Compound 5 has the longest terminal CP bond (1.617 A) of any phosphaalkyne. Due to electron delocalization on the terminal phosphorus atom in 5, fragmentation to a monovalent phosphorus species (CsP (9)) and supermesityl isonitrile (8) is plausible. Isonitrile (8) was isolated in pure form. CsP (9) was trapped as a tricesium pentaphosphorus compound (10) and also as cesium [1,2,4]triphospholide (13).
