Abstract

Several properties of the compound 3,4-dihydro-2H-pyrrole(A1-pyrroline), which has been reported as a component of the male-produced Mediterranean fruit fly pheromone, have been determined by [(1)H]- and [(13)C]nuclear magnetic resonance spectroscopy. The stability of Δ(1)-pyrroline in several solvents and at moderately elevated temperatures has been investigated, and it has been established that it exists as both a monomer and trimer in solution. Although equilibrium studies indicate that the trimer is thermodynamically more stable than the monomer in solution, only the monomer was found in the vapor phase based on infrared analysis.

摘要

[(1)H]- 和 [(13)C] 核磁共振波谱学已确定了被报道为雄性地中海实蝇信息素成分的化合物 3,4-二氢-2H-吡咯（A1-吡咯啉）的几个性质。已经研究了 Δ(1)-吡咯啉在几种溶剂中和中等升高温度下的稳定性，并确定它在溶液中既以单体形式存在，也以三聚体形式存在。尽管平衡研究表明，在溶液中三聚体比单体热力学上更稳定，但根据红外分析，仅在气相中发现了单体。
