AI Article Synopsis
- The compound Bis(1-adamantyl)phosphanylsilylene (1) was heated with various alkynes under microwave conditions, leading to the creation of SiP-heterocycles (3a-d) that exhibit fluorescence and unique isomerization properties from silirene intermediates.
- Additionally, reacting compound 1 with AdC≡P produced a heavy form of cyclopentadiene (4), a process that involves breaking a rarely seen Si(II)-P bond in silylene chemistry.
- This study highlights new chemical transformations and properties associated with silylene derivatives, advancing the understanding of their reactivity and applications.
Article Abstract
Bis(1-adamantyl)phosphanylsilylene 1 was reacted with ArCCR (Ar = Ph, 4-iPr-CH, 3-F-CH; R = H, Ph) at 80 °C under microwave irradiation to afford fluorescence-active SiP-heterocycles 3a-d, which may undergo unique isomerizations starting from silirene intermediates. Moreover, the treatment of 1 with AdCP furnished a heavy congener of cyclopentadiene (4), whose formation involves cleavage of the Si(II)-P bond that is rarely observed in silylene chemistry.
