一般說明
铑是铂族中最稀有的金属之一,在地壳中发现的数量非常少(十亿分之二)。铑的化学性质与它不寻常的基态价电子构型有关,在基态价电子构型中,它最外层的s轨道上只有一个电子。这种电子构型对其催化能力具有重要意义,这使得铑在汽车催化转化器中非常有用。同时,金属铑是一种贵金属,这意味着它具有出色的抗氧化性。
铑的粉末形式是银灰色的,不仅用于汽车工业,还用于化学合成和粉末冶金等其他领域。铑比铂和钯更硬,熔化温度更高,这使它成为合金中有用的硬化元素。此外,它很受欢迎的涂层珠宝和其他物品,因为它提供了一个闪亮的保护层,不容易磨损。

Piperidines are prevalent in natural products and pharmaceutical agents and are important synthetic targets for drug discovery and development. We report on a methodology that provides highly substituted piperidine derivatives with regiochemistry selectively tunable by varying the strength of acid
Organic letters, 15(5), 1064-1067 (2013-02-12)
A method for synthesizing chiral oxazolidinone scaffolds from readily available oxabicyclic alkenes is described. The reaction utilizes a domino sequence of Rh(I)-catalyzed asymmetric ring-opening (ARO) with sodium cyanate as a novel nucleophile followed by intramolecular cyclization to generate oxazolidinone products

A novel rhodium(III)-catalyzed direct functionalization of the ortho-C-H bond of aromatic ketone derivatives and an intramolecular cyclization sequence produced indene derivatives in moderate to good yields. This cascade cyclization involves a conjugate addition of α,β-unsaturated ketone and subsequent aldol condensation.

A new enantioselective rhodium-catalyzed domino reaction is described that gives access to fused heterocycles by desymmetrization of alkyne-tethered cyclohexadienones. Two new C-C bonds and two stereocenters are formed in one step with good enantioselectivity. In contrast to prior reports, it

A concise and highly convergent three-step total synthesis of the lactarane natural product, pyrovellerolactone, is described. The key step involves a regio- and diastereoselective rhodium-catalyzed [(3 + 2) + 2] carbocyclization of an alkenylidenecyclopropane with a 4-hydroxybut-2-ynoate followed by an
