Simple exploration of 2346-26-1

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.

2346-26-1, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular. 2346-26-1, name is Oxazolidine-2,4-dione. A new synthetic method of this compound is introduced below.

To a solution of oxazolidine-2,4-dione (cas: 2346-26-1, 0.1 g, 0.99 O^N^^BOC mmol) in DMF (5 mL) was added /er/-butyl (2-bromoethyl) carbamate ^ (cas: 39684-80-5, 0.265 g, 1.2 equiv.) and K2CO3 (0.274 g, 2.0 equiv.). The reaction mixture was heated to 70 C for 2 hours. The reaction mixture was then cooled to ambient temperature, and quenched with water (20 mL). The aqueous phase was extracted with EtOAc (3 x 20 mL). The combined organic extracts were washed with water, brine, dried (Na2S04), and concentrated under reduced pressure to afford a residue, which was purified by preparative TLC (Petroleum: EtOAc =1 : 1) to provide carbamate 1-280 as a pale yellow oil (0.1 g, 41 % yield). MS (ESI, pos. ion) m/z: 267(M+Na).

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.
