A 2-ethoxycarbonylphosphaferrocene was reduced to the corresponding 2-hydroxymethyl derivative, which was condensed with pyrrole in a 2:1 ratio in the presence of BF3 to give a phosphaferrocene-pyrrole- phosphaferrocene pincer ligand. This tridentate ligand, in turn, reacted with [Rh(acac)(CO)2] to yield a rhodium carbonyl pincer complex. This complex was characterized by X-ray crystal structure analysis and tested in the hydroformylation of internal olefins.

Tripinyltrioxanes of the general formula (I): STR1 in which the radicals Pin are either dextrorotatory (+) or laevorotatory (-) pinyl radicals; a process for the production of (I) by treatment of an enantiomeric mixture of (+)-3-formylpinane and (-)-3-formylpinane (II) with an acid in an organic solvent and fractional precipitation of the trimeric compound (I); and redissociation of (I) into the pure enantiomers (II) with a catalytic amount of an acid.
Resolution of racemic pantolactone

A process for resolving racemic α-hydroxy-β,β-dimethyl-γ-butyrolactone, referred to as D,L-pantolactone, into its optical antipodes, based on the separation of diastereomeric salts of D,L-pantoic acid (α,γ-dihydroxy-β,β-dimethylbutyric acid), produced from D,L-pantolactone, by means of (-)-3-aminomethylpinane, (+)-3-aminomethylpinane or one of their acid addition salts, as a new resolving agent.
