Synthetic Route of 2919-23-5, Adding some certain compound to certain chemical reactions, such as: 2919-23-5, name is Cyclobutanol,molecular formula is C4H8O, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2919-23-5.

General procedure: Solutions of OTMPDMeCN-(X)2 and OTMPDPhCN-(X)2 (10mM, 5mL in CH2Cl2) were prepared from the pre-mixed 1:1 Cu(I)-ligand precursors by addition of excess O2 (1atm) at 193K. Two equiv of substrate per oxidant were used unless otherwise noted. For anaerobic substrate oxidations, excess O2 was removed and the solution was flushed with N2 prior to substrate addition. Similar product distributions were obtained for alcohol oxidation reactions performed under O2 and N2 at 233K. Alcohol oxidations without NEt3 were carried out at 233K, and all other reactions were carried out under N2 at 193K unless otherwise noted. The resulting reaction mixtures were quenched by dropwise addition of aqueous ammonia (30%) until the CH2Cl2 layer turned colorless, and passed through a column of neutral activated alumina (Brockmann I, ?150 mesh, 58A) followed by MeOH (2mL). The copper product is retained, and the organic products elute. The reaction mixture was analyzed by GC/GC-MS. Mass recovery of the products was >90% based on addition of an internal calibrant (benzonitrile for alcohols, acetophenone for amines).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 2919-23-5, Cyclobutanol, other downstream synthetic routes, hurry up and to see.

A quartz glass tube charged with 50 g of catalyst (H1044, composition approx. 27 g of copper oxide, approx. 4 g of chromium oxide, approx. 5 g of barium oxide, on SiO2) and bounded at both ends with Raschig rings was installed in a commercial, electrically heated laboratory tubular furnace and the temperature in the catalyst zone was set to 200 C. 30 g of crude cyclobutanol product (purity approx. 73%, 0.3 mol) were evaporated using a preevaporator and then passed over the catalyst (LHSV=0.18/h). After leaving the catalyst zone, the reaction mixture was cooled using a condenser and collected in a cold trap. 27 g of reaction effluent were obtained, having a composition of 59% of cyclobutanone and 19% of cyclobutanol (conversion: 77%, selectivity: 96%).

Distillation of the product mixture through a 1 m Multifil column provided 102 g of cyclobutanone in a purity of >99% (b.p.: 97-99 C., distillation yield: 67%). Example 8 Gas Phase Dehydrogenation [0044] The quartz glass tube was filled with 50 g of catalyst (H1044, calcined at 700 C.) and was stored in the laboratory tubular furnace as in Example 7.

(LHSV=0.33/h). 127 g of reaction effluent were obtained having an average composition of 58% of cyclobutanone and 2.5% of cyclobutanol (conversion: 97%, selectivity: 82%). Example 9 Gas Phase Dehydrogenation [0045] The quartz glass tube was filled with 50 g of catalyst (H1044, calcined at 650 C.) and stored in the laboratory tubular furnace as described in Example 7. 776 g of crude cyclobutanol (purity: 71%) were then passed in gaseous form over the catalyst at 250 C. (LHSV=0.33/h). 719 g of reaction effluent were obtained having an average composition of 67% of cyclobutanone and 5% of cyclobutanol (conversion: 94%, selectivity: 97%).
