The phrase "a three step reaction" is correct and usable in written English.
It can be used in scientific or technical contexts to describe a process that involves three distinct stages or steps.
Example: "The experiment demonstrated a three step reaction that resulted in the formation of the desired compound."
Alternatives: "a three phase reaction" or "a tri-step reaction".
Based on the good alkaline stability of the model compounds, novel guanidinium-based anion exchange membranes (AEMs), GPP-co-PAEK x, with controlled microblock structures were subsequently designed and synthesized in good yield via a three step reaction that included a fluorophenyl-amine reaction, methylation and nickel (0 -catalyzed coupling.
The major constituent of spearmint essential oil is carvone which is synthesised from GPP in a three step reaction.
A novel phosphorus, nitrogen and sulfur containing monomer, diethyl (acryloyloxy) ethylthiophosphoramidate was synthesized in a two step reaction.
Association of a protein complex follows a two step reaction mechanism, with the first step being the formation of an encounter complex which evolves into the final complex.
The minimum of the ratio q of the two time-constants T1 and T2 (q=T2/T1) describing a two step reaction with ladder structure, at which the second time-constant T2 is recognized, is accepted as a measure for the selectivity evaluation.
Continuous catalytic pyrolysis of high density polyethylene has been carried out for obtaining light olefins in a two step reaction system: (i) thermal pyrolysis in a conical spouted bed at 500 °C; (ii) cracking of the volatiles (mainly waxes, C21+) formed in the first step, in a fixed bed reactor using a catalyst based on HZSM-5 zeolite.
With a couple exceptions, the first synthetic cannabinoids to enter widespread use were called naphthoylindoles, and they are synthesized in a two step reaction where 1-napthoyl chloride, or a substituted derivative, acylates an indole and then the indole nitrogen is deprotonated with a strong base like sodium hydride and alkylated with an alkyl halide like bromopentane.
Hydrogels were activated with a heterobifunctional crosslinker N-Sulfosuccinimidyl-6(4'-azido-2'-nitrophenylamino) hexanoate (Sulfo-SANPAH) (Pierce; Rockfield, IL) in a two step reaction performed in non-amine containing HEPES buffer at pH 8.5.
The panel utilises a two step reaction that consisted of reverse transcription primers and separate PCR primers for each miRNA.
15 [I]DPA-713 was synthesized by a two step reaction from precursor, N,N-diethyl-2-[2- 4-hydroxy-phenyl -5,7-dimethyl-pyrazolo[1,5- α]pyrimidiN,N-diethyl-2-[2- 4-hydroxy-phenyl -5,7-dimethyl-pyrazolo[1,5-a radiochemical purity of >99%.
Although there are no available studies on the catalytic activity of long-chain acyl-CoA synthetase in diatoms; in mammals, they catalyze the formation of long-chain CoA and AMP from fatty acid, CoA and ATP, in a two step reaction that initiates cellular long-chain fatty acid metabolism [ 29].
