Redirect storeview urls with diffrent domain

I would like to redirect some of my store urls for better SEO.
i have 5 storeviews and all of them have diffrent domains.

Example
www.example.de
www.example.eu
www.example.fi
etc.

I tried redirecting using .htaccess and for the main site it works.

Works
RedirectPermanent /catalog/item/1 /newcatalog/item/1

But when i try to redirect other domains it wont work.

Wont work
RedirectPermanent www.example.eu/catalog/item/1 www.example.eu/newcatalog/item/1

How can i do redirects with other domains?
