Donor–acceptor stabilized silaformyl chloride

Author affiliations


Formyl chloride (H(Cl)C[double bond, length as m-dash]O) is unstable at room temperature and decomposes to HCl and CO. Silicon analogue of formyl chloride, silaformyl chloride IPr·SiH(Cl)[double bond, length as m-dash]O·B(C6F5)3 (3) (IPr = 1,3-bis(2,6-diisopropyl-phenyl)imidazol-2-ylidene), was stabilized by Lewis donor–acceptor ligands. Compound 3 is not only the first stable acyclic silacarbonyl compound but also the first silacarbonyl halide reported so far.
