83909-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83909-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,0 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83909-75:
(7*8)+(6*3)+(5*9)+(4*0)+(3*9)+(2*7)+(1*5)=165
165 % 10 = 5
So 83909-75-5 is a valid CAS Registry Number.

Diastereo- and regioselective reactions of π-allyl molybdenum complexes with aldehydes

Krafft, Marie E.,Procter, Martin J.

Remote heteroatom coordination to molybdenum promotes unprecedented selectivity in aldehyde allylation using unsymmetrically substituted allylic metal complexes. (C) 2000 Elsevier Science Ltd.

Copper-Catalyzed Stereospecific Hydroboration of Internal Allylic Alcohols

Ji, Enhui,Meng, Haiwen,Zheng, Yue,Ramadoss, Velayudham,Wang, Yahui

, p. 7367 - 7371 (2019/11/22)

An effective Cu-catalyzed stereospecific hydroboration of aliphatic and aromatic 1,1,2-trisubstituted internal allylic alcohols has been reported. This reaction proceeds via a silyl ether transient protection of allylic alcohols and subsequent stereospecific hydroboration. Followed by an oxidative workup, an array of acyclic, cyclic, and heterocyclic 1,3-diols was synthesized in good to excellent yields with good functional group tolerance and excellent diastereomeric ratios (> 20:1).

Lewis Base-Promoted Ring-Opening 1,3-Dioxygenation of Unactivated Cyclopropanes Using a Hypervalent Iodine Reagent

Gieuw, Matthew H.,Ke, Zhihai,Yeung, Ying-Yeung

supporting information, p. 3782 - 3786 (2018/03/13)

A facile and effective system has been developed for the regio- and chemoselective ring-opening/electrophilic functionalization of cyclopropanes through C?C bond activation by [bis(trifluoroacetoxy)iodo]benzene with the aid of the Lewis basic promoter p-toluenesulfonamide. The p-toluenesulfonamide-promoted system works well for a wide range of cyclopropanes, resulting in the formation of 1,3-diol products in good yields and regioselectivity.
