A structure, comprising a base material, coated with polymer which can be compatible with reduced load against environment and living organisms and various functionalities is provided. The base material is covered with polyhydroxyalkanoate (PHA). The invention also relates to a method for production of the structure comprising immobilizing the enzyme which synthesize PHA on the surface of the base material, biosynthesizing the PHA and coating the base material. The invention also provides toner containing such the structure and production thereof. Further, the invention relates to an image forming method comprising forming the image by providing such toner to the medium to be recorded.

salt and oxone is reported. The preliminary mechanistic investigations suggest that the key factor for achieving the anti-Markovnikov regioselectivity is the semipinacol rearrangement of an iodo functionalized intermediate, which is confirmed by an isotope labeling experiment. In addition, the reaction involves the de-iodination of a co-iodo intermediate via its oxidation to hypervalent iodine species
