Feuerstein,Laurenti,Doucet,Santelli
, p. 43 - 44 (2001)
The cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane/ [PdCl(C3H5)]2 system catalyses allylic amination in good yields with a very high substrate/catalyst ratio; a turnover number of 680 000 and a turnover frequency of 8125 h-1 can be obtained for the addition of dipropylamine to allyl acetate in the presence of this catalyst.
Palladium-tetraphosphine complex: An efficient catalyst for allylic substitution and Suzuki cross-coupling
Feuerstein,Laurenti,Doucet,Santelli
, p. 2320 - 2326 (2001)
A new tetraphosphine, the cis-cis-cis-1,2,3,4-tetrakis (diphenylphosphinomethyl)cyclopentane (Tedicyp) has been synthesized and used in palladium-catalyzed reactions. This tetraphosphine in combination with [Pd(C3H5)Cl]2 affords a very efficient catalyst for coupling reactions. Turnover numbers of 980 000 for allylic amination, 9 800 000 for allylic alkylation and 97 000 000 for Suzuki cross-coupling can be obtained in the presence of this catalyst.

Paragraph 0013; 0014; 0015; 0016; 0017, (2017/04/27)
The invention discloses a preparation method of an allyl amine mixture. The preparation method includes following steps: S1, pouring a catalyst into a reation kettle, adding a certain amount of ammonium hydroxide, rising temperature, and adding chloropropene for ammonolysis reaction; S2, holding the temperature of the step 1, and adding liquid caustic soda; S3, rectifying a reaction product to evaporate water and excessive ammonia; S4, at corresponding temperature, collecting fraction-monoallyl amine; S, at corresponding temperature, collecting fraction-diallyl amine; S6, at corresponding temperature, collecting fraction-trially amine; S7, adding caustic soda flakes into a collected fraction mixture, and performing liquid separation to obtain. The preparation method is mild in reaction condition, ammonium hydroxide is used to replace ammonia in existing methods, and complex ventilation equipment is not needed, so that production cost is saved; by adding the caustic soda flakes, water absorbing effect can be realized, purity of the allyl amine mixture prepared by the method can be effectively improved, and the preparation method is simple to operate, high in yield and worthy of popularization.

Page/Page column 21; 23; 2/13, (2010/01/29)
Methods are provided for the catalytic hydroamination of compounds having an alkyne or allene functional group, in which the compound is contacted with ammonia or an amine in the presence of a catalytic amount of a gold complex under conditions sufficient for hydroamination to occur.
Homogeneous catalytic hydroamination of alkynes and allenes with ammonia
Lavallo, Vincent,Frey, Guido D.,Donnadieu, Bruno,Soleilhavoup, Michele,Bertrand, Guy
experimental part, p. 5224 - 5228 (2009/04/11)
(Chemical Equation Presented) A golden ticket to the synthesis of reactive nitrogen-containing compounds, such as imines, enamines, and allyl amines, through the addition of NH3 to unsaturated bonds is the cationic cyclic (alkyl)-(amino)carbene-gold(I) catalyst shown in blue (Dipp=diisopropylphenyl). An ideal initial step for the preparation of simple bulk chemicals, this reaction is also useful for the synthesis of more complex molecules (see examples).
METHOD FOR PRODUCING PRIMARY AMINE COMPOUND
-
Page/Page column 6, (2008/12/08)
Disclosed is a method for producing a primary amine compound represented by the formula (2) below, which is characterized in that a halogen compound represented by the formula (1) below, ammonia and formaldehyde are reacted with each other, and then the thus-obtained reaction product is [1] brought into contact with an aqueous solution of an acid or [2] reacted with a hydroxylamine under acidic conditions. By this method, a primary amine compound can be commercially advantageously produced by using a low-cost ammonia while suppressing production of a secondary amine as a by-product. (1) (In the formula, R1 and R2 independently represent a hydrogen atom, a C1-C5 alkyl group which may be substituted by a halogen atom or the like, a C1-C5 alkoxy group which may be substituted by a halogen atom, a cyano group, a C2-C11 alkenyl group or a phenyl group or the like; R3 represents a hydrogen atom, a linear or branched C1-C5 alkyl group or a cyano group; and X represents a halogen atom.) (2) (In the formula, R1, R2 and R3 are as defined above.)
