Assembly of organosilver coordination frameworks with aromatic ligands bearing a terminal enediyne group

In a series of five silver(I) complexes synthesized with (2-ethynylbut-1-en-3-yne-1,1-diyl)dibenzene (H2L1) and 9-(penta-1,4-diyn-3-ylidene)-9H-fluorene (H2L2), each resulting ethynide ligand is invariably inserted into a Agn/s

Direct validation of the restriction of intramolecular rotation hypothesis via the synthesis of novel ortho-methyl substituted tetraphenylethenes and their application in cell imaging

We demonstrate a novel synthetic approach to ortho-methyl substituted tetraphenylethene materials, which can be utilised for directly validating the restriction of intramolecular rotation hypothesis as the basic mechanism of aggregation-induced emission phenomenon and cell imaging. This journal is

Sandwich and half-sandwich metal complexes derived from cross-conjugated 3-methylene-penta-1,4-diynes

The cross-conjugated ethynyl-vinylidene [Ph2CC(CCH){C(H)CRu(PPh3)2Cp}]PF6 ([4a]PF6), and [FcC(H)C(CCH){C(H)CRu(PPh3)2Cp}]PF6 ([4b]PF6), and ethynyl-alkynyl Ph2CC(CCH){CCRu(PPh3)2Cp} (5a), and FcC(H)C(CCH){CCRu(PPh3)2Cp} (5b) compounds (Cp = η5-cyclopentadienyl) have been prepared from reactions of the known 3-methylene-penta-1,4-diynes Ph2CC(CCH)2 (3a) and [FcCHC(CCH)2] (3b) with [RuCl(PPh3)2Cp]. The compounds derived from 3b incorporating the more electron-rich alkene proved to be unstable during work-up, and attempts to prepare bis(ruthenium) complexes from 3a and 3b or from transmetallation reactions of the bis(alkynylgold) complex FcCHC(CCAuPPh3)2 (7) with RuCl(PPh3)2Cp were unsuccessful. The related bis-and tris(ferrocenyl) derivatives Ph2CC(CCFc)2 (6a) and FcCHC(CCFc)2 (6b) were more readily obtained from Pd(ii)/Cu(i) catalysed cross-coupling reactions of FcCCH with the 1,1-dibromo vinyl complexes PhCCBr2 (1a) and FcC(H)CBr2 (1b). Cyclic voltammetry of 6a and 6b using n-Bu4N[PF6] as the supporting electrolyte shows broad, overlapping waves arising from the sequential oxidation of the ferrocenyl moieties in electronically and chemically similar environments. Electrostatic effects between the ferrocenyl moieties are enhanced in solutions of the weakly ion-pairing electrolyte n-Bu4N[B{C6H3(CF3)2-3,5}4], leading to better resolution of the individual electrochemical processes. The comparative IR spectroelectrochemical response of 6a and 6b suggest the vinyl ferrocene moiety in 6b undergoes oxidation before the ethynyl ferrocene fragments. There is no evidence of electronic coupling between the metallocene moieties and [6a]+, [6b]n+ (n = 1, 2) are best described as Class I mixed-valence compounds.

Dibrominated addition and substitution of alkenes catalyzed by Mn2(CO)10

A practical method for the dibromination of alkenes without using molecular bromine is consistently appealing in organic synthesis. Herein, we report Mn-catalyzed dibrominated addition and substitution of alkenes only with N-bromosuccinimide, producing a variety of synthetically valuable dibrominated compounds in moderate to high yields.

Iron-Catalyzed Reductive Vinylation of Tertiary Alkyl Oxalates with Activated Vinyl Halides

We present herein a rare and efficient method for the creation of vinylated all carbon quaternary centers via Fe-catalyzed cross-electrophile coupling of vinyl halides with tertiary alkyl methyl oxalates. The reaction displays excellent functional group tolerance and broad substrate scope, which allows cascade radical cyclization and vinylation to afford complex bicyclic and spiral structural motifs. The reaction proceeds via tertiary alkyl radicals, and the putative vinyl-Br/Fe complexation appears to be crucial for activating the alkene and enabling a possibly concerted radical addition/C-Fe forming process.
