碘化

It occurred with poor regioselectivity leading to a mixture of 3-chloro-2,6-difluoro-4-iodopyridine (14; 77%) and 3-chloro-2,6-difluoro-5-iodopyridine (15; 15%) after iodination.

It利达介导的去质子不佳导致混合区域选择性发生在3 -氯-2，6 -二氟- 4 - iodopyridine（14，77％）和3氯- 2 ，6 -二氟- 5 - iodopyridine（15； 15％）后，碘化。

To our surprise, when the amount of iodide was added to 1:1 ratio with samarium, another different reaction occurred to give the iodination product (2Z)-2-alk-2-enoates in high yields.

同样地，结构类似的三氯乙醇酰胺的酯在二碘化钐的促进下也发生了类似的还原消除反应，以高产率得到N-(2，2-二氯乙烯)酰胺，该方法特色是条件温和，反应迅速。

During the iodination process the first product was theγ-AgI which converted in a slow process to β-AgI.

Ag层的厚度增加，晶粒增大，表面粗糙度也随之增大；在Ag层碘化反应过程中刚开始生成的产物是γ-AgI，γ-AgI逐渐缓慢地向β-AgI转化。

Objective To study the prevalence of goiter associated with some factors in Guangzhou after the implementation of universal salt iodization.

However, the mRNA level of Arc showed no significant changes after propofol and bicuculline methiodide administration.

然而， 注入异丙酚和甲碘化荷包牡丹碱后mRNA水平弧无显著变化。

Methods: Male Sprague-Dawley rats received bilateral injection of bicuculline methiodide (10, 50, or 100 pmol/0.5 l) or saline (0.5 l) into the BLA.

雄性SD大鼠被注射甲碘化荷包牡丹碱（ 10 ， 50或100 pmol/0.5 ml ）或生理盐水（ 0.5ml）的BLA。

Under Multislice helical CT guidance, 2.5-5 mL of polymethylmethacrylate mixture （ratio of polymer, moner, ultrafluid iodinated oil was 20 g : 10 mL : 3 mL） had been injected into pathologic pedicles step by step after successful puncture using 13G needle.

在CT引导下，用13G针穿刺到椎弓根，将聚甲基丙烯酸甲酯粉剂、液态单体及超液态碘化油按20g：10mL：3mL的比例配制，当骨水泥呈膏状时，分步注入骨水泥约2.5～5mL。

While compared with routine linearity injection, arc-needle injection 131I-iodinated oil step-by-step sector-shapely through implant C6 glioma and SMMC-7721 hepatoma at subcutis, Rat survival time increased, the body weight kept less descent, their lumps necrose wholely.

对C6、中文提要放射性核素在瘤体内的均匀弥散、持续滞留和辐射剂量估算研究 sMMc一7721的皮下瘤模型瘤内弧形针分段扇形注射'3，I一碘化油，与直行针线状注射相比，动物存活时间长，体重下降少，肿块皇整体坏死。

In chapter 2, the Michael additions of functionalized organozinc iodides with α,β-unsaturated aldhydes, ketenones, esters and l-aryl-2-nitroetheneshave been investigated in the presence of Cu〓/ 2LiCl.

第二章主要研究了在低毒、稳定、易得、价廉的Cu〓存在下，带官能团的有机碘化锌与α，β-不饱和醛、酮、酯及1-硝基-2-芳基乙烯的Michael加成反应，并探讨了反应机理。

This one mode pays close attention to network credence foundation of the businessman very much.
