Asymmetric synthesis of dibenzo[b,d]azepines by Cu-catalyzed reductive or borylative cyclization
A copper-catalyzed asymmetric intramolecular reductive cyclization for the synthesis of dibenzo[b,d]azepines is described. Use of 2′-vinyl-biaryl-2-imines as substrates and in situ formed [CuI/(Ph-BPE)] as the catalyst enables the synthesis of 7-membered bridged...
Supported σ-Complexes of Li‒C Bonds from Coordination of Monomeric Molecules of LiCH3, LiCH2CH3 and LiC6H5 to MoMo Bonds
LiCH3 and LiCH2CH3 react with complex [Mo2(H)2(μ-AdDipp2)2(thf)2] (1 thf) with coordination of two molecules of LiCH2R (R=H,CH3) and formation of complexes [Mo2{μ-HLi(thf)CH2R}2(AdDipp2)2], 5 LiCH3 and 5 LiCH2CH3 , respectively (AdDipp2=HC(NDipp)2; Dipp=2,6-iPr2C6H3 ;...
Plasma Engineering of Microstructured Piezo – Triboelectric Hybrid Nanogenerators for Wide Bandwidth Vibration Energy Harvesting
We introduce herein the advanced application of low-pressure plasma procedures for the development of piezo and triboelectric mode I hybrid nanogenerators. Thus, plasma assisted deposition and functionalization methods are presented as key enabling technologies for...
Unveiling the underlying molecular basis of astaxanthin accumulation in Haematococcus through integrative metabolomic-transcriptomic analysis
Astaxanthin is a valuable and highly demanded ketocarotenoid pigment, for which the chlorophycean microalga Haematococcus pluvialis is an outstanding natural source. Although information on astaxanthin accumulation in H. pluvialis has substantially advanced in recent...
