Decomposition of carbonate esters of 1,3-diols

Decomposition of carbonate esters of 1,3-diols. The chemistry of 1,3-bifunctional systems. XXVI. Bartok, M.; Molnar, A.; Bartok-Bozoki, G. (Dep. 17361-58-9 and 115-76-4 are cas registry numbers. These chemicals are also mentioned in this article. Org. Chem., Jozsef Attila Univ., Szeged H-6720, Hung.). Acta Chim. Hung., 114(3-4), 375-9 (English) 1983. CODEN: ACHUDC. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The decompn. of cyclic carbonates I (n = 0, 1) and II, as well as MeCH(OH)(CH2)nOH (n = 1, 2) and Et2C(CH2OH)2, was examd. in the presence of KOH, KCN, and LiCl. With a large excess of KOH, I and II are transformed into alcs. contg. one C less than their corresponding diols. Other reactions, which are known, include fragmentation to oxo compds., CO2 elimination to give oxetanes, and fragmentation to olefins. .

Preparation of cyclic carbonates and 2-oxazolidones using di-2-pyridyl carbonate

Preparation of cyclic carbonates and 2-oxazolidones using di-2-pyridyl carbonate. Kim, Sunggak; Ko, Young Kwan (Dep. Chem., Korea Adv. Inst. Sci. Technol., Seoul 131, S. Korea). Heterocycles, 24(6), 1625-30 (English) 1986. CODEN: HTCYAM. ISSN: 0385-5414. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Cyclic carbonates, e.g., I (n = 1,2) and oxazolidinones, e.g., II (R = Me, Ph, R1 = H; R = H, R1 = Et) were conveniently prepd. in 80-96% yields by the reaction of diols and b-amino alcs.In this experiment, several chemicals are used like 115-76-4 resp. with di-2-pyridyl carbonate. .
