Well Defined Rich Electronic Structure: Facile Approach for Nido-Carborane Fused Azaspirodecaniums in Water Solution

Abstract

A novel bis-dumbbell shape of a multi cation around a azaspirodecanium combined with nido-carborane was prepared in a single step in good yield starting from pyrrolidine and 1,3-dichloropropane to give one compound and from piperidine and 1,4-dichlorobutane to give the other. This is the first report of an electrolyte azaspirodecanium-boron-cluster structure. 1 H, 13 C, and 11 B nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, and high resolution mass spectrometry (HRMS) methods revealed changes due to interactions among the functional groups. In particular, the compound was electron-rich because of its unique structure and excellent chemical reactivity.

“…Compound 2 was substituted with P-CBMA under alkaline condition to produce water-soluble fluorescent polymer. Bis (4-azoronium [3.4] octane-4-fonium)-o-carborane and Bis (5-azoronium [4.5] decane-5-fonium)-o-carborane [29] were coated in water-soluble fluorophore to obtain the products. The reaction route is as follows (Scheme 1).…”
