Although Scheme 4 shows only linear alkyl-Rh and acyl-Rh intermediates (20-/, 21-/, 17-/, and 22-/), the branched counterparts of these intermediates ( 0-ft, 21-b, 11-b, and 22-6) as well as branched aldehyde R(CH3)CHCHO should be formed when the alkyl-Rh complex formation step yields the branched alkyl-Rh intermediate, R(CH3)CH-Rh(CO)(PPh3)2 (20-6 ), that follows the same subsequent steps as those discussed above (see also Scheme 2). The fact that excess... [Pg.11]

The best reagents for reduction of olefinic aldehydes to olefinic alcohols are lithium aluminum hydride and sodium borohydride. Crotyl alcohol, CHjCH = CHCHjOH, and cinnamyl alcohol, CjH,CH =CHCHjOH, have been prepared in excellent yields. Cinnamyl alcohol is further reduced at higher temperatures to hydrocinnamyl alcohol. Citral, (CHj)jC =CHCHjCHjC(CH3)=CHCHO, may be selectively reduced to the ctOTesponding dienol by catalytic hydrogenation over platinum catalyst. A new method for the preparation of enediol esters of the type... [Pg.527]
