bicyclic and polycyclic ring systems having defined relative and absolute configuration. Approaches that allow the construction of more than one carbocyclic ring at a time have proven valuable, in particular those that allow at the same time the control of an array of new stereogenic centers. One of the most general and most widely used protocols has been the intramolecularDiels-Alder [4 + 2] cycloaddition

complexes [Ph3PR][Au(CN)2Cl2] (R = CH2CH=CHCH3 (I), CH2CN (II)) were prepared by the reactions of organyltriphenylphosphonium chlorides with potassium dichlorodicyanoaurate in water followed by recrystallization from acetonitrile. Apart from the major product II, the crystals of the molecular complex Ph3PC(H)(CN)Au(CN)2Cl (III) were isolated. The products were characterized by X-ray diffraction (CIF

The reaction of sodium chloroiridate with acetonyl-, cyanomethyl-, and 2-butenyltriphenylphosphonium chloride in dimethyl sulfoxide was used to synthesize ionic iridium complexes [Ph3PR][trans-IrCl4(DMSO)(2)] (R = CH2C(O)Me, CH2CN, CH2CH=CHMe). The phosphorus atoms in the [Ph3RP](+) cations have a slightly distorted tetrahedral coordination. The dimethyl sulfoxide ligand in the octahedral anions [trans-IrCl4(DMSO)(2)] is coordinated to metal via sulfur atoms.
