to strengthen the system of image heterogeneity points on methyl free radical

摘要

according to the invention, one or more to know, to form (1) or (2) to take the child to be methyl radical is over me in the mri are useful to provide a free radical.;in the same way, x is oxygen or a table, or the wilderness, or CO machine or s (o) n (here, n is 1 or 3.) in at least one group, and x is the wilderness, or s (o) and s phase;;R1 hydrogen atom or type of - m, - XM, - x - and - Ar2 Ar2 (here, m is the Ar2 is soluble, soluble machine m by random substitution is five or ten dollars and aromatic, and appearance;;each of the two or R7 is hydrogen atom or alkyl, and you will be more silicon aluminum strip that will force you to know leading silicon aluminum strip, and the carbonyl or the same alkyl or together did not accept - or a show or two R7 uae30uac00 they together with atomic carbonyl and free silicon atoms in the body of the loop in order to get carbon five or eight yuan to take the first alkylation, single - or two - i will do the first alkylation, single - or two - not a single place to play, or alkyl or - - t. when the alkyl (but we were random fatigue, the ideal structure in the three following heterogeneity in combination with the atomic valence to be), and the outside of the R7 is hydrogen, hydroxyl, leading to that the arbitrary random. so, you will know in the city, or alkyl or accept a m according to the substitution.;the base has a good stability, long relaxation time and the relaxation of the city.
