that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl‚ or one containing a benzene ring like phenyl[1]. Esters are widespread in nature. Small esters‚ in combination with other volatile compounds‚ produce the pleasant aroma of fruits. It is amazing that so many fragrances and flavors can be

between a double bond and an O–H functional group of an unsaturated alcohol for a metal carbene‚ the O–H insertion product is favoured. The percentage yield as a ratio of ether: cyclopropanol was 81:19 when the ligand on the rhodium catalyst was a methyl group[7]. It was found that changing the ligand in the rhodium catalyst did not alter the reaction[14]. Another example of a X–H insertion reaction is the formation of β-Lactam rings from Rh(II) catalyzed N-H insertion reactions where yields of
