Acetone → Benzophenone oxime

Participants

Reaction Steps

are reacted in each case with 5 g of diphenoxy chloromethane. By a thin-layer chromatographic process (silica gel plates, 9:1 mixture of toluene and acetone as the eluant), practically uniform, oily crude products are obtained, viz. the following diphenoxy-methyloxime ethers: (a) Compound No. 86 (yield: 77% of theoretical), (b) Compound No. 87 (yield: 92% of theoretical), (c) Compound No. 88 (yield: 86% of theoretical), and d) the o-diphenoxy-methyl-benzophenone-oxime designated as Compound No. 89 (yield: 76% of theoretical) which is obtained by recrystallization of the crude product from ether and has a melting point of 89°-90° C.
