The invention provides a rigid tetra-nitrogen four-tooth fourth subgroup metal complex, which has the structure shown in the formula (I): wherein n is 2 - 4. R Is C1 - C30 alkyl, C6 - C30 aryl or substituted aryl of C6 - C30. X Is a halogen, C1 - C30 alky
Tertiary amine self-catalyzed intramolecular Csp3-H functionalization with in situ generated allenes for the formation of 3-alkenyl indolines

A novel methodology for the synthesis of 3-alkenyl indolines through the reaction of in situ generated allenes with N-benzylic Csp3-H has been developed. The reaction was realized by Pd(0) catalyzed allenylation of propargyl carbonate with organoboron and subsequent tertiary amine self-catalyzed Csp3-H functionalization in a one-pot process. Control reactions suggested that the substrate itself might also serve as a Lewis base for the N-benzylic Csp3-H functionalization.

The reaction of 2-fluoro-5-nitrobenzaldehyde with a wide variety of arylamines gives, in general, mixtures of the corresponding 2-arylamino-5-nitrobenzaldehydes and their related anils.Both aldehydes and anils readily underwent acid-catalysed cyclization to give the corresponding 2-nitroacridines.The effect of substituent on the rate of cyclization of these aldehydes and of some related anilino-benzaldehydes and -acetophenones has been studied in trifluoroacetic acid solution by means of 1H n.m.r. spectroscopy.A solution of 2-(N-methylanilino)-5-nitrobenzaldehydein trifluoroacetic acid appears to contain a substituted acridinium ion; treatment of this solution with alkali gave 10-methyl-2-nitroacridone. 1H n.m.r. data for a wide variety of substituted 2-nitroacridines are discussed.
