1.2- DiphenyI-1 -propanone

When optically active 2-amino-1,1-diphenyl-1-propanol is treated with nitrous acid, there is obtained I,2-diphenyI-l-propanone of inverted configuration but lower optical purity than the starting material. Reaction has taken place with... 

Very well studied are arylaliphatic compounds ), especially those which have one double bond. By varying the ratio of carbonyl silane acid, the course of reaction can be immensely influenced. If the ratio is 1 1 10, only the double bond is hydrogenated ) whereas a mixture 1 3 10 hydrogenates both the double bond and the carbonyl function ). When this reducing combination is used in the former ratio, 3-benzoyl-butyric acid yields 4-phenyl-vaIeric acid (722), p.p -dinitrobenzophenone p,p -dinitrodiphenylmethane(123), l,6-diphenyl-hexane-l,6-di-one 1,6-diphenyl-hexane 124) and p-methoxybenzaldehyde p-methoxytoluene (725), respectively ). l,3-Diphenyl-l-propene-3-one gives (depending on the ratio ketone silane acid) 1,3-diphenyl-l-propanone (726) (1 1 10) and 1,3-diphenyI-propane (727) (1 3 10), respectively ).
