A liquid-phase traceless route to 3,5-disubstituted-1,2,4-triazoles has been developed, which allows for the incorporation of two elements of diversity. The heterocycle was constructed upon PEG6000 (soluble polymer) modified by 4-hydroxy-2-methoxy-benzaldehyde, from which a traceless cleavage could be realized with TFA-CH2Cl2. This method provided a library of 3,5-disubstituted-1,2,4-triazoles with high yields and purity. Georg Thieme Verlag Stuttgart.
Diarylacetylenes, enamines and acetylenic polymers and their production

Diarylacetylenes and diarylenamines are synthesized from a Schiff's base and an N-arylmethylheterocycle; these compounds are useful as intermediates for a variety of polymers; in particular an efficient process is provided for producing diaryl acetylenes useful in the efficient production of acetylene group-containing polymers which can be cross-linked to produce high strength polymers free of structural defects such as conventionally arise as a result of liberation of volatiles during the cross-linking.
