摘要： A process for the conversion of alkyl aryl compounds to alkynyl aryl compounds which comprises subjecting said alkyl aryl compounds to chlorination under conditions suitable for the dichlorination of at least one carbon atom of an alkyl substituent to said alkyl aryl compound or monochlorination of adjacent carbon atoms of said alkyl substituent, subjecting the resulting chlorinated alkyl aryl compound to dehydrochlorination in the presence of a basic medium, and thereafter recovering alkynyl aryl compounds.

摘要： A PROCESS FOR THE PREPARATION OF DIALKYNYL ARYL COMPOUNDS WHICH COMPRISES THE STEPS OF (1) INTIMATELY MIXING AT A TEMPERATURE OF 0 TO 150*C. AN AROMATIC DIKETONE OF THE FORMULA
R1-CH2-CO-(X)N-AR-(X)N-CO-CH2-R2
WHEREIN R1 AND R7 ARE RADICALS WHICH MAY BE THE SAME OR DIFFERENT AND WHICH ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND HYDROCARBONYL RADICALS OF 1 TO 10 CARBON ATOMS, X IS AN ALKYLENE RADICAL AND N IS 0 OR AN INTEGER OF 1 TO 6, AR IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF MONONUCLEAR AND POLYNUCLEAR CARBOCYCLIC AND HETEROCYCLIC ARYL RADICALS, AND WHEREIN THE TWO KETONIC RADICALS ARE ATTACHED TO AR, WITH THE REACTION PRODUCT OF AN ACID HALIDE CONTAINING AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF PHOSPHROUS, SULFUR AND CARBON AND AN N,N-DIHYDROCARBONYL SUBSTITUTED AMIDE TO THEREBY PRODUCE A BIS(BETA-HALO-ALPHA, BETA-UNSATURATED CARBONYL) SUBSTITUTED ARYL COMPOUND AND (2) TREATING SAID RESULTING SUBSTITUTED ARYL COMPOUND WITH A BASE SELECTED FROM THE GROUP CONSISTING OF TH HYDROXIDES OF THE ALKALI AND ALKALINE EARTH METALS AND THE ALKOXIDES OF THE ALKALI METALS, AND (3) RECOVERING DIALKYNYL ARYL COMPOUNDS OF THE FORMULA
R1C$C-XN-AR-XN-C$CR2
WHEREIN R1, R2 AR, X AND N ALL CORRESPOND TO THOSE IN THE AROMATIC DIKETONE INTRODUCED INTO STEP (1) ABOVE.
