Three neutral Cu(I) complexes bearing 2,6-dimethylphenyl isocyanide (CNXyl) and different triatomic pseudohalogens (SCN−, OCN− N3−) as ligands were efficiently synthesized characterized. The solid-state structures unambiguously determined through single-crystal X-ray diffraction, revealing unexpected bridging coordination modes in the case of N3−. All tested for azide-alkyne cycloaddition (CuAA...

The performance of trans axially substituted mono-(2 a) and bis(tert-butylisocyanide) (2 b) complexes derived from the highly active bio-inspired iron(II) (pre- )catalyst 2 containing an equatorial macrocyclic tetra N-heterocyclic carbene in homogenous olefin epoxidation catalysis is reported. H2O2 used as oxidant combination with Lewis acid Sc(OTf)3 additive resulting a considerable improvemen...

Irradiation of a toluene solution containing cyclopentadienone tricarbonyl iron complexes and isocyanides with blue LEDs afforded the formation isolation 12 triisocyanide complexes, two which, namely tris(2,6-dimethylphenyl isocyanide)(η 4 -tetraphenylcyclopenatedienone)iron, [Fe(C 9 H N) 3 (C 29 20 O)], tris(naphthalen-2-yl -tetraphenylcyclopenatedienone)iron acetone hemisolvate, 11 7 O)] 2 ·C...

Hexakis(2,6-diisopropylphenylisocyanide)tantalum is the first isocyanide analogue of the highly unstable Ta(CO)6 and represents the only well-defined zerovalent tantalum complex to be prepared by conventional laboratory methods. Two prior examples of homoleptic Ta0 complexes are known, Ta(benzene)2 and Ta(dmpe)3 , dmpe=1,2-bis(dimethylphosphano)ethane, but these have only been accessed via liga...

An efficient and divergent one-pot synthesis of 2,3-dihydro-1H-pyrroles, 3-alkyl-1H-pyrroles and 3-alkenyl-1H-pyrroles from readily accessible 2,4-pentadienenitriles with isocyanide based on reaction condition selection has been described. The reaction of 2,4-pentadienenitriles with ethyl isocyanoacetate undergoes a formal [2 + 3] annulation either to generate 2,3-dihydro-1H-pyrroles in the pre...

Our previous total synthesis of the proposed structures of jiangrines C and D shows that the characteristic data of synthetic samples did not match those of the natural ones, prompting us to revise their structures. Accordingly, we now accomplished the total synthesis of jiangrines A, C and D, which confirms our deduction that their molecular skeletons should compose of 2,3-disubstituted pyrrol...
