       prep. of THF  Bookmark   

I don't know if this is already been posted but whatever. This is a nice patent for the preparation of THF using 1,4-butanediol and an acid catalyst. The patent is from this year. US6316640 (http://l2.espacenet.com/dips/bnsviewer?CY=ep&LG=en&DB=EPD&PN=US6316640&ID=US+++6316640B1+I+)

Thanks, but I believe most people would like to go the other way around... tongue

Can you find any good references on 4-chlorobutanol and/or 4-chlorobutanal from THF too?
