A series of benzobisthiazoles were screened for antiinflammatory activity in the carrageenan paw edema and adjuvant arthritis tests. Compound 26, 2,6-bis(N,N-diethylamino)benzo[1,2-d:5,4-d']bisthiazole, was found to inhibit the swelling of the uninjected paw in the prophylactic adjuvant arthritis model with an ED50 of 2.3 mg/kg orally. As with most compounds of this series, 26 was inactive in acute

Electron-rich ruthenium phthalocyanine complexes were evaluated in carbene transfer reactions from ethyl diazoacetate (EDA) to aromatic and aliphatic olefins as well as to a wide range of aromatic, heterocyclic and aliphatic amines for the first time. It was revealed that the ruthenium octabutoxyphthalocyanine carbonyl complex [(BuO)8Pc]Ru(CO) is the most efficient catalyst converting electron-rich
富电子钌酞菁配合物是首次从重氮乙酸乙酯(EDA)到芳香族和脂肪族烯烃以及各种芳香族,杂环和脂肪族胺的卡宾转移反应中进行评估的。结果表明,八丁氧基酞菁钌羰基络合物[(BuO)8Pc] Ru(CO)是最有效的催化剂,在低催化剂负载和几乎等摩尔的底物条件下,可以将高电子含量和电子贫乏的芳族烯烃转化为环丙烷衍生物,并具有高收率(通常为80–100%)和高TON(最高为1000)。 / EDA比。该催化剂在卡宾插入胺N–H键中显示出罕见的效率。使用0.05摩尔%的催化剂负载量,高胺浓度(1M)和1.1当量。在EDA的作用下,许多结构不同的胺被选择性地转化为单取代的甘氨酸衍生物,其定量收率和周转数均达到2000。高选择性,大底物范围,低催化剂载量和实际反应条件[[BuO)8 Pc ] Ru(CO)是卡宾插入胺中最有效的催化剂。

Novel cyclobutadiene cobalt complex with labile naphthalene ligand [(C4Et4)Co(C10H8)]PF6 catalyzes the insertion of ethyl diazoacetate into X–H bondsgiving the corresponding products in 15–75% yields. The reaction proceeds with primary and secondary aliphatic amines, hydrosilanes and triethylamine borane but not with anilines and alcohols.

A stable and porous porphyrinic metal–organicframework, Ru-PMOF-1(Hf), has been prepared through the self-assembly of [5,10,15,20-tetrakis(4-carboxyphenyl)porphyrinato](monocarbonyl)ruthenium (Ru(TCPP)(CO)) and HfCl4. Single-crystal X-ray diffraction analysis reveals that Ru-PMOF-1(Hf) possesses a three-dimensional (3D) structure with orthogonal 1D open channels of 1.9 × 1.9 nm2. The porous nature
