[reaction: see text] BF(3).OEt(2)-catalyzed atom-transfer radical addition of iodoacetamides to alkynes yielded the corresponding vinyl iodides, which upon treatment with (t)BuOCl and I(2) afforded gamma-lactam derivatives in moderate good yield. The mechanism was proposed be 5-endo amidyl cyclization, vinylic iodine substitution provided driving force for cyclization.
Flexible organic solar cells (FOSCs) are one of the most promising power sources for aerospace aircraft due to their attractive advantages with high power-per-weight ratio and excellent mechanical flexibility. Understanding performance stability high-performance FOSCs is essential further development applications. In this paper, after systematic investigations on state-of-the-art under thermal cycle intensive UV irradiation conditions, in situ tests 35 km stratospheric environment were...
Abstract A concise asymmetric synthesis of triazole antifungal agent voriconazole is described. Salient features this include a LiOH‐controlled highly stereospecific formation ( Z )‐enol triflate from 2‐difluorobenzene acetoacetate to access the crucial tetrasubstituted )‐allylic alcohol, and enantioselective VO(O i Pr) 3 /BHA ligand‐catalyzed epoxidation construct critical contiguous carbon stereocenters in single step.
Adding polypropylene fibre (PPF) to recycled aggregate concrete (RAC) not only improves performance but also has economic benefits. The effects of single-blend and double-blend micro- macro-PPFs in RAC specimens were studied. Micro- used design produce 30 groups PPF-reinforced with 0%, 25% 50% coarse (CA) substitution rates. Controlling the mixing proportions, stress–strain curve, elastic modulus, peak strength, strain acoustic emission amplitude–frequency extremum (AFE) each group obtained....
We examined the effects of temperature on SOC mineralization rate (Cmin) and enzyme kinetic parameters in soils two different latitudinal forests, i.e., broad-leaved Korean pine forest Changbai Mountain at higher latitude evergreen Dinghu lower latitude. The results showed that soil Cmin increased with temperature, Q10(Cmin) were than those soil. maximal rates velocity (Vmax) half-saturation constant (Km) relative to for both β-glucosidase (βG) N-acetyl-β-D-glucosaminidase (NAG), but being...
In order to research the acoustic emission characteristics of polypropylene fiber-reinforced recycled aggregate concrete under uniaxial load, 20 groups test specimens with a coarse substitution rate 25 % and 50 are designed fabricated conduct compression, evolution laws b-value, cracking modes RA-AF moving averages time studied. The influence coarse-fine fiber on b-value RAC discussed. K-means clustering method is adopted for two-dimensional analysis shear tensile cracking, then SVM used...
