A Simple Synthesis and Some Synthetic Applications of Substituted Phosphide and Phosphinite Anions

A New Route to Cationic Half‐Sandwich Ruthenium(II) Complexes with Chiral Cyclopentadienylphosphane Ligands

“…Interestingly, this regioselectivity is the opposite to that found for the nucleophilic opening of phenyl epoxide and phenyl episulfide with lithium phosphides; in that context, the attack of the nucleophile proceeds regioselectively at the less-hindered site. [21] The ring-opening reaction proceeds with complete inversion of the configuration at the stereogenic centre, as is demonstrated by X-ray crystal structure determinations of some derived metal complexes. [12,15] The opposite regioselectivity is observed in the ring-opening reaction of (R)-1-benzylspiro[2.4]hepta-4,6-diene and (S)-1-cyclohexylspiro[2.4]hepta-4,6-diene, which lack the activated benzylic position in the cyclopropane ring.…”

Synthesis and characterization of carboxy-functionalized diiron model complexes of [FeFe]-hydrogenases: Decarboxylation of Ph2PCH2COOH promoted by a diiron azadithiolate complex

“…All solvents were dried with standard methods, distilled before use and stored under nitrogen atmosphere. Ligands Ph 2 PCH 2 COOH and Ph 2 PCH 2 -CH 2 COOH were prepared according to the literature procedures [14]. The adt-and the pdt-bridged all-CO diiron complexes 1 and 2 were synthesized following reported protocols [15][16][17].…”

Chiral Phosphine Ligands in the Structural Chemistry of Gold

“…Racemic (2-hydroxybutyl)diphenylphosphine was prepared according to a modified literature procedure by reaction of potassium diphenylphosphide with 1,2-epoxybutane followed by hydrolysis [8], NMR: Jeol GX 400, Jeol JNM-LA400; CDCI3 as sol vent and internal standard, converted to TMS for 1H and 13C{1H}; H3PO4 (85%) as external standard for 31P{' H}; spectra were measured at room temperature, unless noted otherwise. -MS: Finnigan MAT 90 (fast atom bombard ment).…”

“…It was also antici pated that the presence of a hydroxyl group at the chiral ligand would lead to a directional influence on the solid state structure through the build-up of hydrogen bonds supporting the aggregation through other forces like aurophilicity [7], Synthesis and Structure of 1:1 Complexes A racemic mixture of (2-hydroxybutyl)diphenylphosphine (L) was chosen as a ligand prototype with a center of chirality in its alkyl substituent and with a hydroxyl group as one of the functions at the asymetrical carbon atom. This compound is read ily prepared from potassium diphenylphosphide and 0 9 3 9 -5 0 7 5 /9 7 /1 2 0 0 -1 4 1 ,2-epoxy-butane following a modified literature procedure [8] and may also serve as synthon to prepare further functionalized chiral phosphines or diphosphines.…”
