Lithium Binaphtholate-Catalyzed Asymmetric Addition of Lithium Acetylides to Carbonyl Compounds

The Journal of Organic Chemistry, 2014
The asymmetric addition of lithium acetylides to carbonyl compounds in the presence of a chiral lithium binaphtholate catalyst was developed. A procedure involving the slow addition of carbonyl compounds to lithium acetylides improved the enantioselectivity.

Lithium Polysulfidophosphates: A Family of Lithium‐Conducting Sulfur‐Rich Compounds for Lithium–Sulfur Batteries

Angewandte Chemie, 2013
Sulfur-rich lithium polysulfidophosphates (LPSPs) act as an enabler for long-lasting and efficient lithium-sulfur batteries. LPSPs have ionic conductivities of 3.0×10(-5)  S cm(-1) at 25 °C, which is 8 orders of magnitude higher than that of Li2S. The high lithium ion conductivity imparts excellent cycling performance, and the batteries are configured ...

Lithium Compound Treatment and Psoriasis

Archives of Dermatology, 1979
Observations were made of 12 cases of psoriasis that developed and three cases of psoriasis that became exacerbated during treatment with lithium compounds. Only two patients had a family history of psoriasis, and results of a search for increased frequencies of the histocompatibility antigens seen in psoriasis vulgaris were negative.

Lithium Intercalation in Layer Structured Compound β-ZrNCl

Journal of Inclusion Phenomena, 1984
A layer structured crystal β-ZrNCl forms a lithium intercalation compound LixZrNCl. The upper limit for x determined on the compound prepared by the n-butyl lithium technique is ≈0.29. In the electrochemical process, a pressed β-ZrNCl cathode is further reduced up to x = 1 ∼ 1.25 at potentials as low as 0.8 ∼ 0.6 V relative to Li/Li+.

Syntheses with pyrimidine-lithium compounds

Tetrahedron Letters, 1959
Abstract The principles of the preparation, reactivity and use of organolithium compounds is briefly discussed in relation to recent work with N-heterocyclic derivatives. The synthesis of thymine-C14H3 and 5-ethyluracil from a pyrimidine-lithium intermediate, and the separation of uracil and thymine by ion-exchange chromatography, are described.

Lithium compound treatment and psoriasis.

Archives of dermatology, 1980
Observations were made of 12 cases of psoriasis that developed and three cases of psoriasis that became exacerbated during treatment with lithium compounds. Only two patients had a family history of psoriasis, and results of a search for increased frequencies of the histocompatibility antigens seen in psoriasis vulgaris were negative.

Compound Formation in the Systems Lithium‐Carbon and Lithium‐Boron

Journal of the American Ceramic Society, 1967
The phases present in the 2 to 50 at.% lithium region for the system lithium‐carbon below 700° C are carbon and stoichiometric Li 2 C 2 . The unit cell of Li 2 C 2 was ...
