## Abstract The pyrolysis of ethylene–propylene and ethylene–isobutene mixtures has been studied in a static system over the temperature range of 682°–754° K and for initial pressures of each olefin of 33–300 torr. The following molecular ene reactions were observed and the rate constants measured:
In chloroform solution, the D,L-alteI'nating stereo-co-oligopeptide HCO-L-Phe-(DPhe-L-Phe),-OMe (I) forms three major species, two of which are dimeric and one tetrameric. One of the two dimeric species gives a specific set of 'H-nmr signals at 25°C; the other, together with the tetrameric species,
