Provided are a coating composition for an interconnection part of an electrode and a plasma display panel including the same. Specifically, the coating composition for an interconnection part of an electrode, comprising 0.05 to 2.0 parts by weight of a compound containing a triazole group, 3.5 to 7.5 parts by weight of a silane based compound, and 0.5 to 2.0 parts by weight of a transition metal oxide, is used to effectively prevent opens and short circuits of an electrode due to damage of an interconnection unit caused by gases and humidity in the surrounding environment and due to a migration phenomenon.

Reactions of readily available N-(alkyl-, aryl-, and heteroarylsulfonyl)benzotriazoles 3a-h with diverse nitriles, reactive heteroaromatics, alkylheteroaromatics, sulfones, and esters produced alpha-cyanoalkyl sulfones 5a-i, sulfonylheteroaromatics 7a-e, alpha-(sulfonylalkyl)heterocycles 9a-f, alpha-sulfonylalkyl sulfones 11a-g, and esters of alpha-sulfonyl acids 14a-c, respectively, in synthetically useful to excellent yields. The results represent the first examples of the successful application of sulfonylazoles for C-sulfonylation.

One-pot reactions of sulfinic acid salts (produced from organometallic reagents with SO2) with N-chlorobenzotriazole gave the corresponding N-alkane-, N-arene-, and N-heteroenesulfonylbenzotriazoles 3a-j in 41-93% yields. Reagents 3a-j are efficient sulfortylating agents, reacting at 20-80 degreesC with various primary and secondary aliphatic amines to yield the corresponding sulfonamides in 64-100% yields.

sulfones have been obtained by organocatalytic enantioselectiveMichaeladdition of α-substituted cyanosulfones to vinyl ketones using cinchonaalkaloids as catalysts. The best results were obtained for p-trifluorophenylsulfones by using VIII as catalyst in toluene at −40 °C. Reactions proved to be applicable for a variety of α,β-unsaturatedketones, affording α,α-disubstituted cyanosulfones in excellent
