Otera's catalyst, named after Japanese chemist Junzo Otera, is an organostannane compound which has been used as a transesterification catalyst. This isothioscyanate compound is a member of a family of organostannanes reported by Wasada and coworkers, and elaborated upon by Otera and coworkers.〔
==Preparation==
This class of compounds may be prepared generally by the reaction of an organotin halide and oxide:
: 2 R2SnO + 2 R2SnX2 → (XR2SnOSnR2X)2
In particular, the thiocyanate compound was prepared by the reaction of dibutyltin oxide with dibutyltin diisothiocyanate.〔 Otherwise, this compound is not commercially available.
