    Abstract: 1,222,564. 3,3-Disubstituted oxetanes. FARBWERKE HOECHST A.G. 8 July, 1968 [6 July, 1967], No. 32436/68. Heading C2C. Novel oxetanes of the formula in which R 1 represents an aralkenyl carboxylate radical the alkenyl moiety of which may contain more than one olefinic bond, a benzoylbenzoyloxy radical or a phenoxy radical of the formula in which R 3 , when m and n are 0, represents hydrogen or a methyl or phenyl group, or, when m is 0 and n is 1, represents a #-chloro- or #- phenyl-styryl radical, or, when m is 0 or 1 and n is 0 or 1-1 provided m and n are not both 0, represents a carboxylic or heterocyclic aromatic radical optionally substituted by alkyl, alkoxy, nitro or azido, and R 4 is hydrogen, halogen, alkyl or alkoxy, and R 2 is the same as R 1 or represents hydrogen, halogen, an alkyl, alkoxy or aryloxy group, are prepared by reacting a 3,3-disubstituted oxetane carrying a halomethyl group and an alkyl, alkoxymethyl, aryloxymethyl or benzoylphenoxymethyl group or 2 halomethyl groups in the 3-position with (a) an alkali metal salt of an aralkenylcarboxylic acid or benzoylbenzoic acid or (b) with an alkali metal phenolate of a hydroxybenzaldehyde, hydroxyacetophenone or hydroxybenzophenone, which may be substituted in the OH- bearing ring by halogen, alkyl or alkoxy, and, if desired, condensing a formyl compound so obtained with a ketone CH 3 .CO.(CH=CH) n R 3 (in which n is 0 or 1-4) or condensing an acetyl compound so obtained with an aldehyde R 3 (CH=CH) n 1CHO (in which n 1 is 0 or 1-3), or with α-chloro- or α-phenyl-cinnamaldehyde. The aldehyde/ketone condensation step is effected in an alkaline medium provided by NaOH, preferably at 10-30‹ C. The initial alkali metal carboxylate or phenolate-halomethyl reaction may be conducted at 50-200‹ C. in the presence of a diluent. Specified reactants include 3-methyl or ethyl-3-iodo, bromo- or chloro-methyl-oxetanes and bisiodo, chloro- or bromo-oxetanes and, as aralkenyl acid salts, cinnamates, as hydroxy aldehydes and ketones, p-hydroxyacetophenone, o - hydroacetophenone, p - hydroxybenzaldehyde and p-hydroxybenzophenone, and, as aldehydes or ketones, p-isopropylbenzaldehyde, 4-methoxycinnamic aldehyde,#-(furyl-2)-acrolein, a-phenylcinnamic aldehyde, o-nitrocinnamic aldehyde, 7-phenylheptatrienal, m-azidobenzaldehyde, cinnamic aldehyde, piperonylidene acetone, 9-acetyl-anthracene, cinnarnylidene acetone, benzylidene acetone and benzaldehyde.
