An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.1334177-86-4, name is 1-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-7,10,13,16,19,22,25,28-octaoxa-4-azahentriacontan-31-oic acid. Here is a downstream synthesis route of the compound 1334177-86-4. 1334177-86-4
1334177-86-4, EDCI hydrochloride (8 mg, 0.042 mmol) was added to a suspension of Maleimide-PEG8-acid (25 mg, 0.042 mmol) in dry CH2Cl2 (4 mL) under argon atmosphere. PBD 85 (42 mg, crude) was added straight away and stirring was maintained until the reaction was complete (3 hours). The reaction was diluted with CH2Cl2and the organic phase was washed with H2O and brine before being dried over MgS04, filtered and excess solvent removed by rotary evaporation under reduced pressure by rotary evaporation under reduced pressure. The product was purified by careful silica gel chromatography (slow elution starting with 100% CHCI3 up to 9:1 CHCl3/MeOH) followed by reverse phase HPLC to remove unreacted maleimide-PEG8-acid. The product 86 was isolated in 10% over two steps (6.6 mg). LC/MS 1 .16 min (ES+) m/z (relative intensity) 770.20 ([M + 2H]+ , 40%).
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 1334177-86-4
