B-substituted group 1 phosphides: synthesis and reactivity.

1-Boryl-8-phosphinonaphthalenes 1-BCy-8-PCl-CH (1) and 1-BCy-8-PPhCl-CH (2) were prepared and used as starting materials for the synthesis of B-substituted phosphides. The reduction of 1 and 2 by Mg provided neutral compounds [1-BCy-8-PCy-CH] (3) and [1-BCy-8-PPh-CH] (4). Compound 3 represents the dimer of phosphinoborane 1-BCy-8-PCy-CH while complex 4 is a rare example of a discrete B ← P coordinated diphosphine.

,-coordinated Ru cation: a robust catalyst for aerobic oxidations of benzylamine and benzyl alcohol.

A stable ionic κ,-coordinated Ru complex shows excellent catalytic activity in aerobic oxidations of benzylamine and benzyl alcohol. This complex is stabilized by a stannylene-phosphine -substituted naphthalene ligand, which can act as either a reducing agent for a Ru(III) complex or as a κ,-chelating ligand for Ru(II) compounds.

(N),C,N-Coordinated Heavier Group 13-15 Compounds: Synthesis, Structure and Applications.

The aim of this review is to summarize recent achievements in the field of (N),C,N-coordinated group 13-15 compounds not only regarding their synthesis and structure, but mainly focusing on their potential applications. Relevant compounds contain various types of N-coordinating ligands built up on an ortho-(di)substituted phenyl platform. Thus, group 13 and 14 derivatives were used as single-source precursors for the deposition of semiconducting thin films, as building blocks for the preparation of high-molecular polymers with remarkable optical and chemical properties or as compounds with interesting reactivity in hydrometallation processes.
