General Description

Vinylidene bromide, also known as 1,1-dibromoethene, is a colorless, flammable liquid with a sweet, chloroform-like odor. It is primarily used in the production of copolymers such as polyvinylidene bromide, which are used in the manufacture of heat-shrinkable packaging films, wire and cable insulation, and protective coatings. Vinylidene bromide is also used as a flame retardant and as an intermediate in organic synthesis. However, it is a hazardous chemical and should be handled with caution, as exposure to vinylidene bromide can cause irritation to the skin, eyes, and respiratory system, and prolonged exposure has been associated with adverse effects on the liver and kidneys. Therefore, proper safety measures should be employed when working with vinylidene bromide.

Check Digit Verification of cas no

The CAS Registry Mumber 593-92-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 593-92:
(5*5)+(4*9)+(3*3)+(2*9)+(1*2)=90
90 % 10 = 0
So 593-92-0 is a valid CAS Registry Number.

Catalytic Enantioselective Synthesis of 1,4-Keto-Alkenylboronate Esters and 1,4-Dicarbonyls

Liang, Michael Z.,Meek, Simon J.

supporting information, p. 14234 - 14239 (2019/08/30)

A catalytic enantioselective method for the synthesis of 1,4-keto-alkenylboronate esters by a rhodium-catalyzed conjugate addition pathway is disclosed. A variety of novel, bench-stable alkenyl gem-diboronate esters are synthesized. These easily accessible reagents react smoothly with a collection of cyclic α,β-unsaturated ketones, generating a new C?C bond and stereocenter. Products are isolated in up to 99 % yield with greater than 20:1 E/Z and greater than 99:1 e.r. Mechanistic studies show the site-selectivity of transmetalation and reactivity is ligand dependent. The utility of the approach is highlighted by gram-scale synthesis of enantioenriched cyclic 1,4-diketones, and stereoselective transformations of the products by hydrogenation, allylation, and isomerization.
