Synthesis, structure, and reactivity of rhenium N-isocyanide complexes ReBr(CO)3(CNR)(CNNPPh3)

Rhenium Complexes with p‐Fluorophenylisocyanide

“…This is in accord with other rhenium or technetium complexes of the general composition [M(CO) 3 X(CNR) 2 ]. [12,13,17,18,[23][24][25][26][27][28] The ESI + mass spectrum of 5 shows an intense signal at m/z = 614.914 for the cluster ion {M + Na} + with the expected isotopic pattern. Details are shown in the Supporting Information.…”

Synthesis, Structure, and Transformation of Novel Osmium Azine and Ylide Complexes

“…[cf. the terminal CNNPPh 3 ligands in complexes ReBr(CO) 3 (CNPh)(CNNPPh 3 ) and ReBr(CO) 3 (CNPr)(CNNPPh 3 ) resonate at δ 32.36 and 32.14, respectively] . The heteronuclear 1 H− 13 C (HMQC) spectrum showed that the proton at δ 8.82 was bound to the carbon atom ( C NNPPh 3 ) at δ 155.5 ppm.…”

“…N -Isocyanoiminetriphenylphosphorane (CNNPPh 3 ) is a versatile ligand, which easily substitutes for a more labile ligand to afford metal N -isocyanide complexes and also undergoes nucleophilic or electrophilic reactions . Upon coordination to the metal, the CNNPPh 3 moiety has been reported to further undergo Wittig-type reactions with ketones and aldehydes in the presence of a catalytic amount of acid to form N -isocyanoimine analogues. − Although CNNPPh 3 has been known for many years, only a few related studies concerning its organometallic chemistry have appeared in the literature. − In the course of our continuing studies on the chemistry of metal isocyanide complexes, ,, we have been interested in the reactivity of CNNPPh 3 -containing complexes to try to understand the mediation effect of the metal centers on the property of this coordinated ligand. , Herein we report on the synthesis and transformation of three unprecedented triosmium complexes containing unusual ligands derived from the reaction of CNNPPh 3 with the hydridotriosmium complex H 2 Os 3 (CO) 10 . Their coordination modes are reported here for the first time.…”

Tuning the luminescence of transition metal complexes with acyclic diaminocarbene ligands

“…Although the ADC complexes of both Mn and Re have been previously reported, 122–128 a sole report of luminescent Re i ADC complexes is disclosed. 122 A series of luminescent Re i complexes 81–88 with C , N -ADC was synthesised via the nucleophilic addition of amino-azaheterocycles, namely, 2-aminopyridine, 2-aminothiazole, and 2-aminobenzothiazole, to Re i isocyanides.…”

“…Although the ADC complexes of both Mn and Re have been previously reported, [122][123][124][125][126][127][128] a sole report of luminescent Re I ADC complexes is disclosed. 122 489 nm (87), 499 nm (85), 570 nm (88), and 590 nm ( 86)).…”
