New Heterodifunctional Ligands for Organotransition-Metal Chemistry: Ph2P(CH2)nC5Me4H (n=0, 2)

The synthesis of two new heterodifunctional ligands for organotransition-metal chemistry, Ph2P(CH2)nC5Me4H (n=0, 2), is described.Both compounds are derived from the same intermediate, lithium tetramethylcyclopentadienide.For n=2 the ligand is obtained by a one-pot reaction including two successive nucleophilic substitutions.

Diphosphanylmetallocenes of Main-Group Elements

Several 1,1′-diphosphanyl-substituted metallocenes of magnesium (magnesocenes) were synthesized, structurally characterized, and their reactivity and coordination chemistry were investigated. Transmetalation of these magnesocenes gives access to group 14 metallocenes (tetrelocenes), as well as to group 15 stibonocenes. These s- and p-block metallocenes represent a novel class of bis(phosphanyl) ligands, exhibiting Lewis-amphiphilic character. Their coordination chemistry towards different transition-metal and main-group fragments was investigated and different complexes are presented.
