1 -Phenylethane-1,2,2-tris

C-p position would probably be nearly equal to that of (+)-phenylethane-1,2-diol. The value of the molecular optical rotation differences suggested that p,3,4-tri-hydroxyphenethyl moiety is a racemate. Consequently, the structure of suspensa-side (28) was established as DL- p,3,4-trihydroxyphenethyl-O-a-L-rhamnopyrano-syl-( 1 —>6)-4-0-caffeoyl-p-D-glucopyranoside. [Pg.663]

Methylation is most facile for arylcarbinols and tertiary alcohols. 1,1,1-Tri-phenylethane is readily obtained in high yield from triphenylmethanol, and 1-methyladamantane is formed from adamantane-l-ol. Yields are lower when dehydration is possible. Methylation is not stereospecific the same mixture of epimeric products is obtained from the isomeric 4-f-butyl-l-ethylcyclohex-anols. These features are characteristic of carbonium ion reactions. [Pg.623]

Many years ago, Homer Atkins and his colleagues examined the reduction of triphenylmethane catalysed by nickel powder it went non-selectively to the tri-cyclohexylmethane. 1,3,5-Triphenylbenzene was reduced to the tri-cyclohexylcyclohexane. With phenylethanes, rates decreased slightly with increasing number of phenyl groups. ... [Pg.461]
