The final part of this particular alkyne study108,109,144 involved the electron-rich alkynes ethyl ethynyl ether and diethylpropynylamine. Upon reaction of 221.a or 221.e with ethyl ethynyl ether, the expected adducts 247.j and 247.k were formed. Note that the electron-donating substituent is located... 

The fact that allyltributyltin and styrene which are electroneutral were successfully added to PCTFE led us to the question "Can electron-rich or electron-poor trapping agents be used ". The electron-rich agents that we examined were ethyl ethynyl ether and ethyl vinyl ether. On the side of the electron-poor alkenes, eight were investigated ethyl acrylate, methyl methacrylate, methyl vinyl ketone, acrylonitrile, methacrylonitrile, vinyl bromide, chloromethyl styrene, and 4-vinylpyridine. The details of each reaction are summarized. 

In the case of the electron rich reagents, no addition products were observed, either under catalytic or stoichiometric conditions. In all cases, no evidence of incorporation was discerned from IR analysis. In addition to unidentifiable materials (in the ethyl ethynyl ether case), substantial side reaction could be recognized.

Activation by addition of a carboxylic acid to a triple bond occurs with ethyl ethynyl ether,which forms amides via reactive enol esters. The reaction is catalyzed by mercury(II) oxide under almost neutral conditions. Push-pull alkynes exert higher reactivityThe intermediate enol esters (Scheme 4) rearrange and react with the amino function of a second amino acid. Hydroxy, thiol and imidazole functional groups do not have to be protected. The degree of racemization is low, and yields are good in the case of small peptides. 

Three main areas of the 4-aryl-pyrazolidine-3,5-dione scaffold were modified during the optimization phase towards graminicidal activity and selectivity in small grain cereals. A major breakthrough with regard to the herbicidal activity was achieved as aryl moieties bearing ethyl, ethynyl or methoxy groups in the...
