«Synthesis of 2-(buta-1,3-diynyl)-N,N-dimethylanilines using reductive methylation step»

Mendeleev Commun., 2014, 24, 102-104

DOI: 10.1016/j.mencom.2014.03.013

Synthesis of 2-(buta-1,3-diynyl)-N,N-dimethylanilines based on reductive methylation of ortho-iodoanilines using CH2O–NaBH3CN and coupling with terminal diacetylens was developed. Altered sequence including dimethylation of 2-(buta-1,3-diynyl)anilines was also successfully achieved and gave higher overall yields in the case of anilines without acceptor substituent in the ring.

“Metal-mediated cyanamide–hydroxyguanidine coupling” Inorg Chim. Acta, 2015, 425, 114-117

DOI: 10.1016/j.ica.2014.10.015

Reaction of the cyanamides R₂NCN (R = Me 2a, Et 2b) with the hydroxyguanidine OC₄H₈NC(=NOH)NH₂ (1) in the presence of zinc halides leads to [ZnX₂{HN=C(NR₂)ON=C(NH₂)NC₄H₈O}] derived from the ZnIImediated cyanamide–hydroxyguanidine coupling. This reaction is the first observation of interplay between any nitrile group and any hydroxyguanidine both in metal-involving and metal-free chemistry. Complexes 3a,b–5a,b rather rapidly degrade in solutions at RT, but solvates 3a,b MeOH and 4a MeOH are sufficiently stable in the solid state and they were characterized by IR, HRESI⁺-MS, solid state CP-MAS TOSS ¹³C NMR, and X-ray crystallography (for 3a,b). Complexes 4b and 5a,b were identified in solutions by HRESI⁺-MS.

“Trifluoromethylated allyl alcohols: acid-promoted reactions with arenes and unusual ‘dimerization’”

Tetrahedron Lett., 2014, 55, 6851-6855

DOI: 10.1016/j.tetlet.2014.10.083

An unusual ‘dimerization’ of CF₃-allyl alcohols [ArCH=CHCH(OH)CF₃] under the action of anhydrous FeCl₃ was found to give fluorinated indanes in 62–90% yields via the formation of intermediate allyl cations. Reactions of CF₃-allyl alcohols with arenes (Ar′H) led to CF₃-alkenes [Ar(Ar′)CHCH=CHCF₃] in 48–75% yields. The mechanisms of the transformations are discussed.
