powerful reagents in organic synthesis, but the risks associated with their toxicity and instability often limit their uses. Herein we describe an efficient, easy-to-handle and safe batch protocol for the in situ generation and cyclopropanation of these highly reactive non-stabilized diazoalkanes through the oxidation of free hydrazones using iodosylbenzene. Numerous substituted cyclopropanes have been

The present invention provides: a light diffusing agent which enables the achievement of a resin molded body having excellent light diffusibility, light transmission properties, surface hardness and the like; a resin composition which contains this light diffusing agent; and a molded body. One embodiment of the present invention provides a light diffusing agent which contains a copolymer that contains a (meth)acrylate constituent unit (A) represented by general formula (1) and a polyvalent vinyl constituent unit (B) that is copolymerizable with the constituent unit (A).
