Page/Page column 18, (2016/04/20)
Provided are a process for preparing an N ortho acyl substituted nitrogen-containing heterocyclic compound and an aminal iron (II) complex thereof, and the use of the complexes obtained by the process in an olefin oligomerization catalyst. The N ortho acyl substituted nitrogen-containing heterocyclic compound in the present invention is for example 2-acyl-1,10-phenanthroline or 2,6-diacetyl pyridine as shown in formula b, and the N ortho acyl substituted nitrogen-containing heterocyclic compound in the present invention is produced by a reaction of a precursor thereof in a substituted or unsubstituted nitrobenzene. Preferably the precursor shown in formula I in the present invention is produced by 1,10-phenanthroline reacting with trialkyl aluminum, or a halogenoalkyl aluminum RnAIXm, or a substituted or unsubstituted benzyl lithium Ph′CH2Li, followed by hydrolysis. The preparation method provided in the present invention has a few synthetic steps, an easy process, a low toxic effect, and reduces the preparation costs of the catalyst, and has a promising outlook in the industrial application.

An efficient method towards synthesis of 1,10-phenanthrolines is described. Through Lewis acid-catalyzed annulation reaction between 3-ethoxycyclobutanones and 8-aminoquinolines, a variety of unsymmetric and symmetric 1,10-phenanthroline derivatives were

(Chemical Equation Presented) 2-Substituted pyridine, quinoline, isoquinoline, bipyridine, and 1,10-phenanthroline analogues of benzylic acetates undergo Sml2-promoted coupling with aldehydes and ketones to afford (2-hydroxyalkyl)heteroaromatics.

The synthesis and antimycoplasmal activity in the presence of copper of a series of 1,10-phenanthrolines and 2,2'-bipyridyls are presented. It is shown that the unsubstituted parent compounds have the lowest activity. Introduction of substituents in one or both of the orthopositions raises the activity, alkyl groups having the most pronounced activity enhancing effect. Generally 1,10-phenanthrolines are 2-4 times more active than corresponding 2,2'-bipyridyls.
