Page/Page column 4-5, (2008/06/13)
A process for producing phenylacetic acid is provided. The process includes combining sodium, chlorobenzene, toluene, and a catalyst to form a suspension. This suspension is mixed to form phenylsodium. Upon boiling, the suspension forms benzylsodium. The suspension is then carbonized and acidified to form phenylacetic acid.

There is disclosed a method of preparing benzyl metal compounds represented by general formula (2), comprising reacting a phenyl metal compound represented by general formula (1) with toluene, in the presence of a catalytic amount of amine. According to this method, benzyl metal compounds can be prepared at a high yield, and in an industrially advantageous manner. Further, there is also disclosed a method of preparing 4-phenyl-1-butenes, comprising reacting the benzyl metal compound obtained in the method, with an allyl halide. STR1 wherein M represents an alkali metal, STR2 wherein M has the same meaning as the above.
Tetrahydroquinoline derivatives

The invention relates to new tetrahydroquinoline derivatives which are intermediates useful in the preparation of anti-ulcer agents. The new derivatives have formula (I) STR1 wherein M is sodium, potassium or lithium, R1, R2, R3, R4, R5 and R6 are the same or different and represent hydrogen, or a lower alkyl, or a phenyl radical, and any of R4, R5 and R6 may be a gem-di-lower alkyl radical.
Alkali metal-containing, organometallic products
-
, (2008/06/13)
An alkali metal-containing, organometallic product, which is hydrocarbon-soluble, is prepared by reacting an organo-alkali metal reactant in which the alkali metal atom is bonded to a carbon atom, e.g. cyclohexyl-lithium, with a di(organooxy)-alkaline earth metal reactant, e.g. di-n-butoxy-magnesium, in an organic solvent at about -20° to +120°C. The organo-alkali metal reactant can be prepared by reacting an organo halide with an alkali metal, and this can be done in situ, i.e. in the presence of the di(organooxy)-alkaline earth metal reactant. The organometallic product has approximately the same chemical reactivity as the organo-alkali metal reactant from which it is prepared, but is more soluble in hydrocarbon solvents.
