Paragraph 00395, (2017/09/05)
The present invention relates to novel manganese complexes and their use, inter alia, for homogeneous catalysis in (1) the preparation of imine by dehydrogenative coupling of an alcohol and amine; (2) C-C coupling in Michael addition reaction using nitriles as Michael donors; (3) dehydrogenative coupling of alcohols to give esters and hydrogen gas (4) hydrogenation of esters to form alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di- lactones), or polyesters); (5) hydrogenation of amides (including cyclic dipeptides, lactams, diamide, polypeptides and polyamides) to alcohols and amines (or diamine); (6) hydrogenation of organic carbonates (including polycarbonates) to alcohols or hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (7) dehydrogenation of secondary alcohols to ketones; (8) amidation of esters (i.e., synthesis of amides from esters and amines); (9) acylation of alcohols using esters; (10) coupling of alcohols with water and a base to form carboxylic acids; and (11) preparation of amino acids or their salts by coupling of amino alcohols with water and a base. (12) preparation of amides (including formamides, cyclic dipeptides, diamide, lactams, polypeptides and polyamides) by dehydrogenative coupling of alcohols and amines; (13) preparation of imides from diols.

Reaction of N-hydroxyphthalimide (4) with equivalent amounts of aliphatic and aromatic primary amines gives the N-substituted phthalimides (7), while with excess of these amines if gives the diamides (8) of phthalic acid.The reaction of 4 with t-butyl amine gives only the butyl monoamide (9a) of phthaloylhydroxamic acid.N-Methoxyphthalimide (5) reacts in the same manner.Compound 4 does not condense with epichlorohydrin, but condense with epibromohydrin to give N-(2,3-epoxypropoxy)phthalimide (6) which on reaction with equivalent amounts of aliphatic primary amines gives the N-substituted phthalimides (7) and with excess of the amines it gives the diamides (8) of phthalic acid.The reaction of 6 with aromatic primary amines gives only the N-arylphthalimides.Secondary amines do not react with 6.

The reactions of N-naphthylmethyleneaminophthalimides (1a, b) with Grignard reagents took place either by normal addition to one of the carbonyl groups to give 2a, d, or by 1,2-addition and cleavage to give 4-arylphthalaz-1-ones (4a-d).The reactions of 1a, b with amines gave 5, 6 and 7, respectively.

N-(Arylmethyleneamino)phthalimides (2a-c) carrying an o-substituent in the aryl group were prepared by the reaction of N-aminophthalimide with o-substituted benzaldehydes.The reaction of these compounds with Grignard reagents proceeded either by normal addition to one of the carbonyl groups to give 3a-c or by addition and cleavage to give 4-arylphthalaz-1-ones 5a-c.The steric effect exhibited by either the Grignard reagent or the N-arylmethylene compound was studied.The reaction of N-furfurylideneaminophthalimide (2d) with Grignard reagents was also investigated.N-( Arylmethyleneamino)phthalimides reacted with primary amines to give N,N'-dialkylphthalamides (7a and b) while the reaction with secondary amines gave (8a and b).

The reaction of phthaloyl chloride with primary amines, which leads to the formation of the N,N'-substituted diamides of phthalic acid, takes place through the intermediate formation of the N-substituted isophthalimides.The reactivity of these compounds i

Macrocyclic phthalic acid diamides were obtained by the reaction of N,N'-substituted diphthalimides with polyoxyethylenediamines, while the corresponding tetraamides were obtained with primary aliphatic amines.It is shown that the reaction is a thermodynamically controlled process.
