摘要
The parent patent claimed the prodn. of aldehydes and ketones by oxidn. of prim. or sec. alcohols with O2 using a catalyst comprising at least 2 salts or metal complexes (A) and (B) of formula: M1XnLm (A) and M2ZpL'q (B). Where M1 is ruthenium; x and z are anions; n is 2 or 3, m is 0-3, or 6; p is 1-3; M2 is Fe or Cu, q is 0-6, and L and L' are water or an organic cpd. The process is esp. useful for prodn. of phenoxy-substd. benzaldehyde cpds. which are intermediates for pyrethroid insecticides. The current addition claims the use of ruthenium trifluoroacetate as cpd. (A).
