Cyanogen halides are known substances for the cyanating reaction. There are a few evidences for bromination reaction too. On the other hand carbenes are known as very important substances due to their remarkable reactions. Unfortunately carbenes at room temperature are very unstable and there is not a simple method for preparation of them. In most cases the isolation is not possible. We have reported a new reliable and fast preparation method of almost stable carbenoids. The mechanism of the formation has been discussed.

A new, fast and easy method for one-pot reaction of aromatic aldehydes and dialdehydes with malononitrile and cyanogen bromide has been developed to afford full substituted 3-arylcyclopropane-1,1,2,2-tetracarbonitriles in excellent yields in very short time (about 5 seconds). The structures elucidations were characterized by IR, 1H NMR, 13C NMR, mass spectrometry and X-ray crystallography techniques. For these compounds the crystallographic data showed two structures in mirror image in solid case and one distinct structure in solution. The reaction mechanism was discussed.
