supporting information, p. 876 - 880 (2017/06/27)
A palladium-catalyzed oxidative vicinal diazidation of alkenes has been developed, in which TMSN3 was used as azide source. Both styrenes and unactivated alkenes are suitable for this reaction. And trans-alkyldiazides were obtained as major products from cyclic alkenes with moderate to good diastereoselectivities. This reaction afforded an efficient way for the synthesis of useful 1,2-diamines after hydrogenation.

Souto, Jose A.,Gonzalez, Yolanda,Iglesias, Alvaro,Zian, Debora,Lishchynskyi, Anton,Muniz, Kilian
supporting information; experimental part, p. 1103 - 1111 (2012/07/17)
A rapid and productive vicinal diamination of alkenes takes place in the presence of a hypervalent iodine(III) reagent and bissulfonimides as nitrogen sources. A total of more than 60 examples are presented. The reaction is characterized by its robustness and its wide substrate scope: it proceeds selectively with both terminal and internal alkenes and tolerates a range of functional groups.

, p. 291 - 292 (2007/10/03)
Convenient method for preparation of 1,2-diamine from the corresponding nitroolefin was established by successive reactions of Michael addition of O-ethylhydroxylamine to nitroolefin and reduction with hydrogen. The present preparative method was applicable to various nitroolefins by one-pot procedure.

, p. 1005 - 1010 (2007/10/02)
Oxime ethers 1 react with ammonia and primary amines to give α-amino oxime ethers.The reaction of α-bromo oxime ethers with sodium azide affords α-azido oxime ethers.Hydrogenolysis of the azido compounds using 5percent palladium on calcium carbonate as catalyst yields the α-amino oxime ethers.The reaction of α-azido oxime ethers with lithium aluminum hydride gives 1,2-ethanediamine derivatives.The reaction of azido oxime ether 13 with LiAlH4, and subsequently the reaction of the resulting mixture of the diamines 14 and 15 with phosgene, preferably gives cis-4-pentyl-5-methyl-2-imidazolidone (16) indicating that the reduction of 13 proceeds in a stereoselective manner to furnish mainly the syn-1,2-ethanediamine 15. Key Words: Oxime ethers / α-Azido oxime ethers / α-Amino oxime ethers / 1,2-Ethanediamines
