Appeal No. 94-3474
Application 07/956,126
in which
11 12
R and R independently of each other denote
hydrogen, halogen or COHal,
13 12
R is hydrogen, halogen or COHal, where R
and R , if they are adjacent, can form the radical of13
a 5- or 6-membered isocyclic or heterocyclic ring,
which itself can be monosubstituted or disubstituted by
halogen or COHal, where such heterocyclic rings contain
1 or 2 hetero atoms selected from the group comprising
N, O and S, and
X is chlorine or bromine,
and where, in the case of the occurrence of SOHal
2
groups, these are converted to halogen with elimination
of SO , without ultraviolet irradiation and without the
2
addition of free-radical generators, wherein the
halogenation is carried out at a temperature of 120 -
240EC and in the presence of one or more alkali metal
halides selected from the group comprising KCl, KBr,
RbCl, RbBr, CsCl and CsBr in an amount of 0.1-30 mmol
of alkali metal halide per mol of the methylaromatic
compound, provided that when X is chlorine, only the
alkali metal chlorides are used, and when X is bromine,
only the alkali metal bromides are used.
The Rejection
Claims 1 and 4-16 stand rejected under 35 U.S.C. § 112,
first paragraph, on the ground that the expressions “without
ultraviolet irradiation” and “without the addition of free-
radical generators” recited in claim 1 do not have support in the
specification as originally filed.
