Upon interaction with a Lewis acid v(CO) decreases for the basic CO in all three of the above-mentioned bases, with the order of decrease being (CH3)2C=O C=O moiety, and such an interpretation is borne out by vibrational spectroscopic data. For example, a v(CO) vs. bond order ...
On exposure to 2,4-dinitrophenylhydrazine, (CO)2(NO)Cr(η5-C5H4CHO) (1) formed the corresponding hemi-aminals, which readily lose water [11] to form an imine derivative 4 in the presence of a Lewis acid BF3 with a yield of 65%. Analogous reactions between 2,4-dinitrophenylhydrazine ...
