Remarkable activation of an alkyne [2+2+2]-cycloaddition catalyst, 2-iminomethylpyridine (dipimp)/CoClmiddot;6H/Zn, by a phthalate additive

A catalyst for alkyne [2+2+2]-cycloaddition reactions, 2-(2,6- diisopropylphenyl)iminomethylpyridine (dipimp)/CoClmiddot;6H/Zn, can be effectively activated by addition of a catalytic amount of dialkyl phthalate to enable reactions that cannot proceed under unactivated conditions. The activation by adding phthalate was ligand- and solvent-dependent, and it was unique to dipimp and N-methyl-2-pyrrolidone (NMP). With use of diphosphine ligand instead of dipimp or with use of tetrahydrofuran (THF) instead of NMP, no activation by a phthalate additive was observed. This simple method of catalyst activation with use of inexpensive, commercially available compounds is highly practical and may find many applications. Georg Thieme Verlag Stuttgart · New York.

Efficient activation of 2-iminomethylpyridine/cobalt-based alkyne [2+2+2] cycloaddition catalyst by addition of a silver salt

The addition of silver triflate (AgOTf) or silver hexafluoroantimonate (AgSbF6) significantly increased the activity of the 2-(arylimino)methylpyridine/cobalt(II) chloride hexahydrate (CoCl 2·6O H2O)/zinc catalyst in alkyne cyclotrimerizations thereby accelerating the reaction and enabling the use of unactivated, simple internal alkynes as the monoyne substrate : The rate of reaction was found to be highly dependent on the nature of the counter anion (X-) and the ligand (L) in the postulated cationic cobalt(I) complex [LCo(I)]+X-.
