2- Butyl-l-phenyl

Arylcyclopropanes can be prepared from a variety of alkenes enamines react sluggishly,63 electron-rich alkenes are, in general, the most reactive. Thus, phenylcarbene, generated by dirhodium tetraacetate catalyzed decomposition of phenyldiazomethane, gave 2-butyl-l-phenyl-cyclopropane (2) in 6% yield from hex-1 -ene, but l-butoxy-2-phenylcyclopropane (3) was obtained in 92% yield from butyl vinyl ether.64... 

In the presence of dicarbonylrhodium chloride dimer [Rh(CO)2Cl]2, 1-benzoyl-2-propylcyclo-propene reacts with hex-l-yne to give 2-butyl-7-phenyl-4-propyloxepin (1, R = Pr) in 62% yield together with 2-butyl-6-phenyl-3-propylphenol. With methyl prop-2-ynyl ether and 4-phenyl-but-l-yne, 2-(methoxymethyl)-7-phenyl-4-propyloxepin (54%) and 7-phenyl-2-(2-phenylethyl)-4-propyloxepin (45%) are formed together with small amounts of the isomeric phenols.87... 

The lithium enolates of cyclopentanone and cyclohexanone undergo addition-elimination to the 2,2-dimethylpropanoic acid ester of ( )-2-nitro-2-hepten-l-ol to give 2-(l-butyl-2-nitro-2-propenyl)cycloalkanones with modest diastereoselection. An analogous reaction of the enolate ion of cyclohexanone with the 2,2-dimethylpropanoic acid ester of (Z)-2-nitro-3-phenyl-2-propenol to give 2-(2-nitro-l-phenyl-2-propenyl)cyclohexanones was also reported. The relative configuration of these products was not however determined6.
