There is no need for the recovery of the catalyst in the fluorous biphasic transesterification catalyzed by Cl (C6F13CH2CH2) 2SnOSn (C6F13CH2CH2) 2Cl2 (1; see scheme), which results in quantitative conversions and yields. An FC-72 solution of the dimeric fluoroalkyldistannoxane 1 can be recycled repeatedly without having to recover the neat catalyst.
