The unusual geminal hydrogenation of a propargyl alcohol derivative with [CpXRuCl] as the catalyst entails formation of pianostool ruthenium carbenes in the first place; these reactive intermediates can be intercepted with tethered alkenes to give either cyclopropanes or cyclic olefins as the result of a formal metathesis event. The course of the reaction is critically dependent on the substitution pattern of the alkene trap.

The E isomers of leaf alcohol and its structural analogs differing in the length of the carbon chain, the presence of substituents at various positions of the molecule, the position of the double bond, and replacement of the double bond by a three-membered ring were synthesized.Many representatives of the Z and E series have a herbal odor, and similarity is observed in the odor of the respective pairs of Z and E isomers.The proximity of the odor of the investigated compounds to the standard (leaf alcohol) is determined by the number of carbon atoms in their molecules.

Dichlorobis(triphenylphosphine)platinum(II) is an effective catalyst precursor for the carbonylation of organic iodides having β-hydrogens on saturated sp3 carbons.The carbonylation under carbon monoxide pressure in the presence of alcohol gives esters, and aldehydes are obtained by the reaction under carbon monoxide and hydrogen pressure.Thus, 1-iodohexane is carbonylated to methyl heptanoate in 79percent yield in the presence of methanol at 120 deg C under 70 kg cm-2 of initial carbon monoxide pressure.Heptanal is formed in 86percent yield from 1-iodohexane at 120 deg Cunder carbon monoxide (50 kg cm-2) and hydrogen (50 kg cm-2).Alkenyl und alkynyl iodides are also smoothly carbonylated in the presence of alcohol into the corresponding esters without reduction of unsaturated bonds.

Dichlorobis(triphenylphosphine)platinum(II) is an effective catalyst for the carbonylations of organic iodides having β-hydrogens attached to sp3-carbons to give the corresponding aldehydes and esters in the presence of molecular hydrogen and alcohol, respectively.
