cyclo propane + H2/ni catalyst --> propane..

Could anyone tell me the simple mechanism for this rxn?

H2/catalyst opens smaller ring like cyclopropane and cyclobutane ONLY...reason I am not sure 😛 Sorry

so it'll make cyclo to normal by opening the ring?

 

[dennisDDS]

are you sure its cyclopropane?

because h2/catalyst add H across a double bond.. SYN addition

so cyclopropene to cyclopropane..

So here's the deal w/ cyclopropane:

1. It has high Baeyer strain.
2. It has double bond character due to its isomerization with propene.

Thus, it is very reactive, and it responds to catalytic hydrogenation in a similar way that an alkene would (by yielding its corresponding straight-chain alkane).

The same can be said for cyclobutane, which is, however, slightly less reactive.
