Using Catalysts to Make Catalysts: Titanium-Catalyzed Hydroamination to Access P,N-Ligands for Assembling Catalysts in One Pot

Using a diamido-bis(amidate) titanium precatalyst, the hydroamination of alkynylphosphines afforded phosphinoenamine products. After reduction, 2-aminophosphines are prepared in excellent yield and on gram scale. A broad variety of alkynylphosphines and primary amines with different electronic and steric features are tolerated in this sequential transformation, enabling the rapid assembly of a collection of ligands. Additionally, intermediate phosphinoenamines can be used directly as proligands for coordination to transition metals using protonolysis or salt metathesis reactions. These transformations result in easy-to-use one pot protocols to prepare metal P,N-complexes for catalysis or small molecule activation.

Chromium catalysts for ethylene trimerization/tetramerization functionalized with ortho-fluorinated arylphosphine ligand

A series of novel asymmetric bidentate phosphines with ortho?fluorine substituents was developed and characterized. In combination with chromium, the compound gave high activity to 1-hexene and 1-octene (approaching 3200 kg/g Cr/h) and high combined selec

Selective deprotection of Me3Si-/Ph2P(O)-protected arylalkynes: Methyl Grignard reagent-promoted dephosphorylation of Ph2P(O)-protected alkynes

A Ph2P(O)-protected alkyne underwent dephosphorylation by treatment with MeMgBr in THF with Me3Si-protection untouched. The dephosphorylation followed by a transition-metal-catalyzed coupling of the resulting terminal a lkyne with aryl halides was carried out in a one-pot manner to afford the desired coupling product. Selective deprotection of Me3Si-/Ph2P(O)-protected alkynes enabled facile syntheses of expanded π-systems such as cyclic phenyleneethyny lenes and unsymmetrically substituted ditriazol.
