An efficient and selective Cu-catalysed hydrohydrazination of terminal alkynes with parent hydrazine is reported. The methodology tolerates a broad range of functional groups, allows for the synthesis of symmetrical and unsymmetrical azines, and can be extended to hydrazine derivatives and amines.
Synthesis of 2,5-dihydroisothiazole derivatives. 2*. 3-aryl(hetaryl)-substituted 2-alkyl-5-arylimino-2,5-dihydroisothiazoles

, p. 87 - 102 (2014/05/06)
A series of new 2-alkyl-5-arylimino-2,5-dihydroisothiazoles, substituted at position 3 with aryl and hetaryl groups and not substituted at position 4 was prepared by oxidative cyclization of N-arylamides of 3-alkylaminoprop-2- enethioic acids. The formation of the starting thioanilides was investigated by reacting the respective N-alkylimines of acetophenones with isothiocyanates. The main by-products were identified and characterized.

A process for forming a conjugate of a polyoxyalkylene polymer (such as polyethylene glycol) with a compound containing an amine group(s) and/or a sulfide group(s) by reacting the compound with an acrylate terminated polyoxyalkylene (such as polyethylene
N-Fluoro-bis[(trifluoromethyl)sulfonyl]imide: Electrophilic fluorination of imines and some methyl-substituted pyridines
Ying,DesMarteau,Gotoh
, p. 15 - 22 (2007/10/02)
Direct fluorination of imines with N-fluoro-bis[(trifluoromethyl)sulfonyl]imide 1 afforded mono and/or difluoroketones without the need of a strong base to first generate the imine anions. Structurally related 2- and 4-methyl-substituted pyridines gave the respective fluoromethyl pyridines with 1. Our results suggest that an enamine intermediate plays a key role in these reactions.
Alkynylmercury Chloride or Acetate as Intermediates in the Mercury(II) Salt-promoted Addition of Aliphatic and Aromatic Amines to Terminal Acetylenes
Barluenga, Jose,Aznar, Fernando,Liz, Ramon,Rodes, Rosa
, p. 1087 - 1091 (2007/10/02)
Arylaminomercuriation of terminal acetylenes has been carried out with aliphatic amines to yield amines and enamines.Phenylethynylmercury chloride is shown to be an intermediate in the mercury(II) salt-promoted addition of aliphatic and aromatic amines to terminal alkynes.
