Proton abstraction from the methylene position of a cycloproparene provides the corresponding C1 anion that can be intercepted by a carbonyl-containing compound to provide a wide range of novel methylidenecycloproparenes. The physical and chemical aspects of this comparatively new class of surprisingly stable, strained compounds have been explored. The present account provides a perspective on these developments from the initial experiments in the Utah laboratories.

naphtho-fluoranthene polycyclic aromatic hydrocarbons (PAHs) with MW = 302 (C24H14) was synthesized via a Pd-catalyzed fluoranthene ring-closing reaction. By understanding the various modes by which the palladium migrates during the transformation, structural rearrangements were bypassed, obtaining pure PAHs in high yields. Spectroscopic and electrochemical characterization demonstrated the profound diversity
通过Pd催化的荧蒽闭环反应合成了MW = 302(C 24 H 14)的12种二苯并蒽和萘并荧蒽多环芳烃(PAHs)库。通过了解转变过程中钯迁移的各种模式,可以绕开结构重排,以高收率获得纯净的PAH。光谱和电化学表征证明了异构体之间电子结构的巨大差异。突出可见光发射方面的显着差异,该PAHs库将使它们的标准化能够用于毒理学评估和作为光电材料的潜在用途。
