New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Arca, M, once mentioned the application of 938-18-1, Name is 2,4,6-Trimethylbenzoyl Chloride, molecular formula is C10H11ClO, molecular weight is 182.65, MDL number is MFCD00013650, category is thiomorpholine. Now introduce a scientific discovery about this category, Electric Literature of 938-18-1.
The reactions between the donors morpholine (1) and thiomorpholine (2) with I-2 in low polar solvents (C6H6, CHCl3, CH2Cl2) and different donor/I-2 concentration ratios (1:1, 1:2, 1:3) yield solids of stoichiometry 1 . I-2, 1H(+)I(3)(-), 1H(+)I(5)(-), 2 . I-2, and 2H+I-3(-). Crystals suitable for X-ray structure determination have been obtained only for 1H+I-3(-). All the solids were characterized by FT-Raman and FT-IR spectroscopies in the region ofthe v(I-I) frequencies. Studies in solution have been carried out on each of the reactions between 1, 2, and N-methylmorpholine (3) with I-2. The formation constants of the 1:1 adducts of 2 and 3 determined at 20 degrees C by UV-visible spectroscopy are 8500 and 8400 dm(3) mol(-1), respectively. IR spectroscopy shows that I-2 binds the nitrogen of 1 and 2 both in axial and equatorial positions. Further FT-Raman and C-13 NMR spectroscopies support the nature of weak adducts berween 1 (2) and the molecular diiodine in solution. (C) 1997 John Wiley & Sons, Inc.
