Preparation and reactions of (beta-trifluoromethyl)vinyl sulfonium salt.

(Beta-trifluoromethyl)vinyl sulfonium salt as a novel three-carbon fluorinated building block was conveniently prepared from easily available (beta-trifluoromethyl)vinyl sulfide and diphenyl iodonium salt in excellent yield. This easily handled crystalline reagent displayed two types of useful transformation involving aziridination and vinylation to afford the corresponding trifluoromethylated compounds in excellent yields.

Nocturnal hypoxemia after lobectomy for lung cancer.

Background: Although nocturnal episodic hypoxemia after major abdominal surgery has been reported, the condition of nocturnal oxygen saturation after lung surgery is largely unknown. We evaluated nocturnal oxygen saturation during the perioperative period after lobectomy for lung cancer. This study also compared the postoperative course of nocturnal oxygen saturation after standard lobectomy with posterolateral thoracotomy and lobectomy with video-assisted thoracic surgery.
