The present invention relates to the field of perfumery. More particularly, it concerns some derivatives of formula 5 in the form of any one of its stereoisomers or a mixture thereof, and wherein R1 represents a hydrogen atom, a C1-4 alkyl or alkenyl group, or a (CHR)2OH group, each R being a hydrogen atom or a methyl group; R2 represents a hydrogen atom or a 10 methyl, ethyl or n-propyl group; and R3 represents a hydrogen atom or a methyl group; as well as their use as perfuming ingredients. The present invention concerns also the compositions or articles containing said compounds.
An efficient and commercial phosphorylation process of a complex alcohol, such as secondary and tertiary alcohols, with P4O10 at high temperatures, and a product obtained by the process.

spectrometry. The molecular structures of H2L1 and 1 have been confirmed by single crystalX-ray diffraction. Based on the above studies, an octahedral coordination geometry around the metal center has been proposed for 1–4. To investigate the catalytic effectiveness of 1–4, the complexes have been used as catalysts in β-alkylation of secondary alcohols with primary alcohols and synthesis of quinolines. The
摘要 一系列新的钌 (II) 羰基配合物 [RuCl(CO)(EPh3)2(L1-2)] (1-4)(E = P 或 As;H2L1 = 水杨醛达嗪,H2L2 = 2-羟基萘达嗪),由钌 (II) 前体 [RuHCl(CO)(EPh3)3] 和双齿 ON 供体席夫碱配体 (H2L1-2) 组装而成。配体及其新的钌 (II) 配合物均已通过元素分析、光谱方法(UV、IR、NMR(1H、13C、31P)以及 ESI 质谱法进行表征。H2L1 和 1 的分子结构已通过单晶 X 射线衍射。基于上述研究,围绕金属中心的八面体配位几何结构已被提议用于 1-4。为了研究 1-4 的催化效果,配合物已被用作 β-烷基化的催化剂仲醇与伯醇的合成和喹啉的合成。研究了溶剂、时间、碱、催化剂负载和配体部分的取代基对反应的影响。值得注意的是,1 是一种更有效的催化剂,可用于广泛的醇和喹啉合成的烷基化。检查了催化剂的
