The deprotonated cyanoketenate [NCCCO] - is isoelectronic with carbon suboxide (O=C=C=C=O), which has been widely studied as the structure and bonding situation in this molecule is ambiguous between a linear heterocumulene structure or a bent motif. Despite numerous attempts by chemists to generate cyanoketene and the cyanoketenate anion using various techniques, the unusual connectivity and reactive nature of these molecules have posed challenges. Consequently, scientists have only succeeded in trapping them in low-temperature matrices or detecting them through mass spectrometry, achieved by subjecting precursors to heat and irradiation. Therefore, a synthetically approachable methodology for the generation of cyanoketene and cyanoketenate is highly desired.
