A method has been devised to cross couple acid chlorides using tributyltin fluoride (BU3SnF) and polymethylhydrosiloxane (PMHS) in Stille coupling. This method employs Bu3SnF and PMHS as an in situ tin hydride source while performing the experiment in one pot. These techniques avoid the toxic tin intermediates commonly associated with Stille couplings.
