Ionic Liquid-Supported Photocatalysts: A Reusable Environmentally Friendly Oxidation Reaction System That Uses Air and Light.

Ionic liquids are used in various fields due to their unique physical properties and are widely utilized as reaction solvents in the field of synthetic organic chemistry. We have previously proposed a new organic synthetic method in which the catalyst and reaction reagents are supported on ionic liquids. This method has various advantages, such as the ability to reuse the reaction solvent and catalyst and its facile post-reaction treatment. In this paper, we describe the synthesis of an ionic liquid-supported anthraquinone photocatalyst and the synthesis of benzoic acid derivatives using this system. This synthesis of benzoic acid derivatives via the cleavage of vicinal diols by an ionic liquid-supported anthraquinone photocatalyst is an environmentally friendly process, and furthermore, it has a simple post-reaction process, and the catalyst and solvent can both be reused. To the best of our knowledge, this is the first report on the synthesis of benzoic-acid derivatives via the cleavage of vicinal diols using light and an ionic-liquid-supported catalyst.

[Difficult Perioperative Glucose Management in a Type 2 Diabetic Patient with Anti-insulin Antibody Undergoing Laparoscopic Partial Liver Resection].

A 50-year-old man with type 2 diabetes mellitus was scheduled for laparoscopic partial liver resection. Six months prior to the surgery, he developed frequent hypoglycemic attacks and was diagnosed as anti-insulin antibody positive. The operation was performed under general anesthesia with epidural anesthesia. Intermit- tent and continuous insulin administration was required during liver resection due to persistent hyperglycemia. After termination of the liver resection, the patient exhibited uncontrolled hypo- and hypergly- cemia, and recovery from anesthesia was delayed due to severe hypoglycemia. He recovered immediately after 40% glucose administration. However, frequent glucose administration was required for two hours after transfer to the ICU due to hypoglycemia. It should be born in mind that preoperative poor glucose control might be caused by anti-insulin antibodies and lead to difficult perioperative glucose management.
