Preparation of （ R ）- and （ S ）-2-Allyl-1,3,2-Dinaphtho （α,β）[d. f]dioxaborepin and Their Reactions with Aldehydes

(R)- and (S)-2-Allyl-1,3,2-dinaphtho(α,β) [d.f]dioxaborepin ((R)-2 and (S)-2) have been first prepared by the reaction of (R)-( )- or (S)-(-)-1, l‘‘-bi-2-naphthol and triallylborane in THF at room temperature, respectively.(S)-2 and (R)-2 are sensitive to moisture and oxygen in air and disproportionate easily to triallylborane and 1, l’-bi-2-naphthyl bis(1, l‘‘-bi-2-naphtholborate) at ambient temperature. However, THF is a stabilizer for them. The reactions of (R)-2 or (S)-2 and some aliphetic or aromatic aldehydes in CH2Cl2 at -78℃ for several hours afforded β-alkylenyl alcohols in up to 84.8G ee. Among them, optically active 1-(3,5-dichlorophenyl )-3-butenol and 1-( 2-methoxyphenyl )-3-butenol were first prepared.

Relativistic mapping between NMR and NSR

We highlight three aspects of NMR(nuclear magnetic resonance)and NSR(nuclear spin-rotation):(1)Relativistic theory of NMR:The nonrelativistic theory of NMR was established in 1950 by Ramsey,butthe corresponding relativistic counterpart was long plagued by the’missing’diamagnetism.This was fully resolved only in 2007.(2)Relativistic theory of NSR:The nonrelativistic theory of NSR was also established in 1950 by Ramsey.

Effects of anions on the biosorption of microelement cations by macroalga <Emphasis Type="Italic">Enteromorpha prolifera</Emphasis> in single- and multi-metal systems

The results of research on the effects of anions on the biosorption of microelement cations by the edible marine macroalga Enteromorpha prolifera in singleand multi-metal systems are discussed in this paper. It was shown that the maximum biosorption capacity (qmax) in a single-metal system of Co(II) ions decreased in the following sequence: Cl- (46.0 mg g-1) > SO42- (42.8 mg g-1) > NO3- (41.9 mg g-1). In multi-metal systems, in which the ratios of Cl-, NO3-, and SO42- were 0:0:4, 1:1:2, 3:0:1, and 4:0:0, there were clear differences among the biosorption capacities. In all the examined systems (other than the 0:0:4 system), inhibition of the binding of microelement cations by the macroalga was observed. In all the systems, the highest value of qmax was obtained for Cu(II) cations; the value ranged from 31.9 mg g-1 in 0:0:4 (SO42- only) to 18.2 mg g-1 in 4:0:0 (Cl-only).
