I have a copper pipe connected to a pex pipe by a leaking sharkbite fitting. I'd like to replace the sharkbite fitting with something more permanent. However I'm not sure if it's safe to use a soldered fitting since the copper pipe only extends two or three inches from the piece of wood it runs through.
Is there a way to safely solder this or are there any other permanent copper fittings which don't require heat to attach?

Use a soldering mat and that will protect the wood.
If you don’t have a soldering mat, then anything that will stop direct flame contact with the wood will work - I have used non-flamnable fibre board very effectively. Good because you can cut a slot with a hole to fit around the pipe.
More of an issue will be getting that copper pipe clean and using a decent flux - I use Powerflux in those situations as it is very strong but you do need to wash it after.
