Amidoamine-based dendrimers with end-grafted Pd–Fe units: Synthesis, characterization and their use in the Heck reaction

Fabrication of a label-free electrochemical immunosensor using a redox active ferrocenyl dendrimer

“…Dichloromethane was used from a MBRAUN (MB-SPS 800) solvent drying and purification system. As starting materials, the H 2 N end-grafted dendrimer (1) 26 and ferrocene carboxylic acid fluoride (2) 27 were prepared according to the published procedures. 28 All other reagents were used as received from commercial suppliers.…”

Fundamental study of (ferrocenylethynyl)phosphines: Correlation of steric and electronic effects in C,C cross-coupling reactions

“…One advantage of the Heck reaction is its trans selectivity. As catalysts, for example, phosphapalladacycles [13], various palladium(II)eacetate/phosphine systems [9], palladium nanoparticles [27], and N-heterocyclic carbene palladium complexes [11] have been applied. Within this work, complexes 6e, 6f, and 7aef were used in the coupling of iodo benzene with tertbutyl acrylate (Reaction 3) in a mixture of tolueneeacetonitrile (ratio 1:1, v:v) in presence of NEt i Pr 2 at 80 C with a catalyst loading of 0.5 mol% (Experimental Section, From Table 4 it can be seen that the catalyst featuring sterically demanding tolyl (7b) and mesityl phosphines (7c), or weekly sdonating furyl ligands (7d) are best suited for C,C couplings under the above mentioned conditions.…”

Au nanoparticles stabilised by PEGylated low generation PAMAM dendrimers: Design, characterisation and properties

“…Di(ethylene glycol) ethyl ether acrylate (10) was distilled prior to use. The (poly)amidoamine dendrimers N(CH 2 CH 2 C(O)NHCH 2 CH 2 NH 2 ) 3 (6), [CH 2 N(CH 2 CH 2 C(O)NHCH 2 CH 2 NH 2 ) 2 ] 2 (7), and (H 2 NCH 2 CH 2 NHC(O)CH 2 CH 2 )N[CH 2 CH 2 NCH 2 CH 2 C(O)NHCH 2 CH 2 NH 2 ) 2 ] 2 (8) as well as the corresponding di(ethylene glycol) functionalised amidoamine (R 2 NCH 2 CH 2 NHC(O)CH 2 CH 2 ) N[CH 2 CH 2 N (CH 2 CH 2 C(O)NHCH 2 CH 2 NR 2 ) 2 ] 2 (5b, R = CH 2 CH 2 C(O)O (CH 2 CH 2 O) 2 C 2 H 5 ) were synthesised according to previously published procedures [33,34,37].
