2-OXETANONE DERIVATIVE AND PROCESS FOR PRODUCTION THEREOF
An aldehyde derivative represented by the general formula (2) is reacted with ketene in the presence of a Lewis acid catalyst to produce a novel 2-oxetanone derivative (1), which is then purified to a 2-oxetanone derivative having a high trans-isomer puri

Liquid crystals based on hypervalent sulfur fluorides. Part 4. [1] Pentafluorosulfanyl alkanes and olefins
New liquid crystals with a pentafluorosulfanyl function as their polar terminal group were prepared and fully characterized. The synthetic key step was the triethyl borane-catalyzed addition of SF5Br to a suitable olefin precursor, followed by
