C-S addition onto a terminal alkyne with rhenium

Kazuhiko Takai and co-workers have reported in Organic Letters on a rhenium catalyzed C-S bond addition onto a terminal alkyne. We don’t usually see much of rhenium chemistry out there, but when there is something, it seems to be interesting.

Rhenium Catalyzed Approach to Aminoindanes

Kazuhiko Takai and co-workers at Okayama University have published in Organic Letters on a rhenium catalyzed cyclization reaction between an arylimin and allene to form amino-indanes.

Didehydroxylation with Rhenium

Dihydroxylations of olefins is a common technique to make 1,2-diols – however, recently in JACS, the Bergman and Ellman team have published on the reverse reaction using a rhenium catalyst.

Rhenium Catalyzed CO2 Insertion

Did you know that rhenium can insert CO2 into an epoxide?  Here’s a DFT study of this reaction led by Hai-Shun Wu and co-workers from Shanxi Normal University.

Transposition of Allylic Alcohols not the Matrix

Armen Zakarian and co-workers at UCSB have recently published in JACS on an allylic alcohol transposition using a rhenium oxide catalyst – a terminal alcohol transfers position with the internal alkene to yield an internal alcohol and terminal olefin.
