Pr(III) and Nd(III) are hard acceptors in HSAB (hard and soft acid base) sense and hence are known to exhibit practically a little affinity towards electrons. At the same time these metal ions show strong preference for oxygen donor chelating...

Derived No Effect Level (DNEL(inh)) has been set for occupational exposure to but-2-yno-1,4-diol according to REACH principles. Maximum allowable concentration (MAC) and DNEL(inh) have been compared. Experimental data from two inhalation studies on rats and three oral studies have been...
R A Jedrychowski et al.
Journal of applied toxicology : JAT, 12(2), 117-122 (1992-04-01)
2-Butyne-1,4-diol was given to male and female Wistar Imp:DAK rats by oral gavage for 28 consecutive days in daily doses of 1, 10 or 50 mg kg-1 day-1. After 28 days all animals were necropsied. Blood samples were obtained and...
Douglass F Taber et al.
The Journal of organic chemistry, 73(4), 1605-1607 (2008-01-17)
The conversion of 2-butyn-1,4-diol to (Z)-2,4-diiodobut-2-en-1-ol proceeded efficiently using in situ generated trimethylsilyl iodide. Coupling with Grignard reagents and other nucleophiles delivered (2Z)-2-iodo allylic alcohols. The geometry of the products was established by nOe.
But-2-yne-1,4 diol, primary gloss improver and contact sensitizer in a nickel plating bath.
K E Malten
Contact dermatitis, 6(4), 286-287 (1980-06-01)
R A Jedrychowski et al.
Journal of applied toxicology : JAT, 12(2), 113-115 (1992-04-01)
Acute toxicity of 2-butyne-1,4-diol (BYD) was evaluated in laboratory animals. The evaluation involved acute oral and dermal toxicity in rats, dermal and ocular irritation in rabbits and skin sensitization in guinea pigs. The oral LD50 values for BYD were 132...
Homologation method for preparation of substituted pentacenes and naphthacenes.

Molecules (Basel, Switzerland), 23(9) (2018-09-12)
Morpholine- and bis(2-methoxyethyl)amine-substituted 1,3,5-triazine derivatives containing an alkoxy-o-carborane in the 6-position of the triazine ring were successfully synthesized. The molecular structures of the methoxy- and ethoxy-o-carboranyl-1,3,5-triazines were established by X-ray crystallography. In vitro studies showed that the methylene bridged morpholine-...
