, p. 913 - 919 (2003)
Alkylation of N-(phosphorylalkyl)phosphazenes 2 with methyl iodide and allyl bromide and acylation with ethyl chloroformate leads to the formation of aminophosphonium salts 4 derived from (aminoalkyl)phosphonates. N-(Phosphorylalkyl)amidines 8 were obtained by reaction of phosphazenes derived from aminophosphonates with benzoyl chloride and subsequent addition of amines. These functionalized amidines were used as key intermediates in the synthesis of oxazolin-4-ylphosphonates 9 and 10. In a similar manner, oxazolin-4-ylphosphane oxides 17 and 18 were prepared from N-(phosphanylalkyl)amidines 16, which were obtained by reaction of phosphazenes derived from phosphane oxides 15 with benzoyl chloride and amines.

Diarylphosphine- and dialkylphosphine-containing compounds, processes of preparing same and uses thereof as tridentate ligands
-
Page/Page column 36, (2012/12/13)
A novel process of preparing tridentate ligands containing one or more of a diarylphosphine and/or dialkylphosphine electron donating groups are disclosed. Use of this process for preparing a combinatorial library of such tridentate ligands and of organometallic complexes containing same is also disclosed. Further disclosed are novel diarylphosphine-containing and dialkylphosphine-containing compounds that can serve as tridentate ligands (e.g., pincer ligands), combinatorial libraries of such tridentate ligands, organometallic complexes containing these ligands (e.g., pincer complexes), and combinatorial libraries of such complexes. Methods utilizing these libraries for screening for candidate organometallic catalysts are also disclosed. Novel precursor molecules useful for preparing the tridentate ligands and processes of preparing same are also disclosed.
