Abstract
Terminal olefin is prepared by bringing together (1) a compound having the formula ##STR1## wherein Cp is a .pi.-cyclopentadienyl radical, R is terminal alkyl and X is an essentially non-interfering monovalent entity, and (2) a mono-olefin having a carbon skeleton different from that of R under reaction conditions to displace R from (1) by (2). This process is especially useful in isomerization of internal olefins to the corresponding terminal olefins.

A process which comprises bringing together (1) a compound having the formula ##STR13## wherein each Cp is a .pi.-cyclopentadienyl radical, R is terminal alkyl and X is an essentially non-interfering monovalent entity and (2) mono-olefin having a carbon skeleton different from that of R under reaction conditions to displace R from (1) with (2).
A process for isomerizing an internal olefin to a terminal olefin, which process comprises the following steps:
- (A) subjecting (1) a compound having the formula ##STR15## wherein each Cp is a .pi.-cyclopentadienyl radical, R is terminal alkyl and X is an essentially non-interfering monovalent entity and (2) internal mono-olefin having a carbon skeleton different from that of R to reaction conditions under which R is displaced from (1) by (2) forming (3) a compound having the formula ##STR16## wherein Cp and X have their aforedescribed significance and R' is terminal alkyl having the same carbon skeleton as (2) and
- (B) subjecting (3) formed by Step (A) and (4) mono-olefin having a carbon skeleton different from that of R' to reaction conditions under which R' is displaced from (3) by (4) forming terminal olefin having the same carbon skeleton as (2).
