Abstract A facile ruthenium‐catalyzed regio‐ and stereoselective hydroboration of symmetrical, aromatic 1,3‐diynes with pinacolborane towards 2‐boryl‐1,4‐diaryl‐buta‐1‐en‐3‐ynes their further transformation into potassium trifluoroborate salts is presented. The reaction proceeded efficiently for 1,4‐diphenylbutadiynes various substituents on the phenyl rings heterocyclic 1,4‐di(thiophen‐3‐yl)buta‐1,3‐diyne. resulting products were isolated fully characterized ( 1 H, 13 C, 11 B 1D NOESY NMR,...
Abstract A simple method for the synthesis of new bio‐based silane coupling agents (SCAs) with a terpene aromatic core by functionalization cheap, natural eugenol and its sulfur derivatives using hydrosilylation C=C bonds HSi(OEt) 3 , followed nucleophilic substitution reactions OH/SH groups is presented. The obtained alkoxysilanes possess different polymer‐reactive functionalities (alkenyl, epoxide, thiirane, thiocarbamoyl, thioester, thioether moieties). This group biogenic SCAs was fully...
Hydrosilylation of borylalkynes to borylsilylalkenes (with a different arrangement substituents) has been successfully developed. The cis-addition SiH group the CC bonds was directed by using specific catalyst. obtained products are crucial synthons for introduction CC in organic synthesis.
The cyclotetramerization reaction following the Linstead approach led to novel symmetrical magnesium(II) aminoporphyrazines with methyl(6-bromo-3-pyridylmethyl) and methyl(4-bromobenzyl) substituents. These products were applied in demetallation procedure trifluoroacetic acid dark, which resulted free-base porphyrazine derivatives. Then these macrocycles remetallated iron(II) bromide DMF give desired iron(III) macrocycles. Simultaneously, of maleonitrile derivatives manganese(II) chloride...
New coupling agents for fuel-saving “Green Tires” were synthesized by selective hydrosilylation of olefins or alkynes with 2,4,6,8-tetramethylcyclotetrasiloxane.
The first, recyclable protocol for the selective synthesis of (E)-alkenyl boronates via borylative coupling olefins with vinylboronic acid pinacol ester in monophasic (cat@IL) or biphasic (cat@IL/scCO2) systems is reported this article. efficient immobilization [Ru(CO)Cl(H)(PCy3)2] (1 mol%) [EMPyr][NTf2] and [BMIm][OTf] subsequent extraction products n-heptane permitted multiple reuses catalyst without a significant decrease its activity stability (up to 7 runs). Utilization scCO2 as an...
A novel approach towards synthesizing new metalloid-substituted olefins has been accomplished by transforming (
A new method for the repetitive batch silylative coupling (trans-silylation) of vinylsilanes with vinyl boronates in presence Ru(CO)Cl(H)(PCy3)2 immobilized poly(ethylene glycols) (PEGs) has been developed. Three PEGs (PEG600, PEG2000, and MPEG2000) different molecular weights end groups (MW = 600–2000) were tested as solvents immobilization media, while an aliphatic solvent (n-hexane or n-heptane) supercritical CO2 was used product extraction. By applying 2 mol % Ru–H catalyst, it possible...
In this paper, we compare the reactivity of a series triaryl borates B(OArx)3 as catalysts for hydroboration alkenes and alkynes. It was observed that commercially available B(OPh)3 performed poorest, whereas with o-F atoms appeared to perform much better.
