2- Ethyl-1-butene

The reaction of ethylene at -20°C and 1 atm with the phosphine-free catalyst prepared from 77-allylnickel chloride and ethylaluminum dichloride in chlorobenzene results in the rapid formation of a mixture of ethylene dimers with lesser amounts of higher oligomers. The dimer fraction consists mainly of 2-butenes and the trimer fraction of 3-methylpentenes and 2-ethyl-1-butene as well as a minor amount of hexene (97). From the composition of the products it can be concluded that the displacement reaction predominates over the insertion reaction when using the phosphine-free catalyst and that the direction of addition of both the H—Ni and C2H5—Ni species is mainly of the Ni — C2 type. [Pg.121]

In a similar way, methylene moieties can be achieved by employing siliconeo-pentylmagnesium chloride (287) to carry out a methylenation 190. If 3-pentanone (257) is treated with 287,2-ethyl-1-butene (288) is formed (Scheme 39). For further applications of the Peterson reaction and its modification, see also64,191,192. ... [Pg.59]

Use the formula prefix + root + suffix to put the name together. The full name of this compound is 2-ethyl-1-butene. Remember that a hyphen is placed between numbers and letters, and commas are placed between consecutive numbers. [Pg.556]

Ans. Two more isomers. Less of 2-ethyl-1-butene due to steric constraints at the Rh center. [Pg.166]

The IR spectra of both products show the characteristic absorptions of alkenes in the regions 3020-3100 cm-1 and 1650 cm-1. However, in the region 700-1000 cm-1, 2-ethyl-1-butene shows a strong absorption at 890 cm-1 that is typical of 2,2-disubstituted R2C=CH2 alkenes. The presence or absence of this peak should help to identify the product. (3-Methyl-2-pentene is the major product of the dehydrobromination reaction.)... [Pg.284]
