136809-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136809-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,0 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136809-07:
(8*1)+(7*3)+(6*6)+(5*8)+(4*0)+(3*9)+(2*0)+(1*7)=139
139 % 10 = 9
So 136809-07-9 is a valid CAS Registry Number.

A New Version of the Peterson Olefination

General, green, and scalable synthesis of imines from alcohols and amines by a mild and efficient copper-catalyzed aerobic oxidative reaction in open air at room temperature

Tian, Haiwen,Yu, Xiaochun,Li, Qiang,Wang, Jianxin,Xu, Qing

supporting information, p. 2671 - 2677,7 (2012/12/12)

A general, green, and scalable synthesis of the useful imines and a,b-unsaturated imines is successfully achieved by a low-loading and powerful, mild and efficient copper-catalyzed aerobic oxidative reaction of alcohols and amines in the open air at room temperature under base- and dehydrating reagent-free conditions. This practical reaction can use air as the economic and green oxidant, tolerates a wide range of substrates, can afford high yields of the target imines on a large scale, and produces water as the only by-product, and thus being the best imination method as yet using alcohols and amines directly.

PREPARATION OF (E)-α,β-UNSATURATED AROMATIC ALDEHYDES BY HIGH STEREOSELECTIVE OLEFINFORMYLATION.

Gaudemar, Marcel,Bellassoued, Moncef

, p. 349 - 352 (2007/10/02)

Treatment of acetaldehyde N-ter-butylimine by two equivalents of LDA, followed by trimethylsilyl chloride trapping affords the α,α-disilylated imine; the latter reacts with aromatic aldehydes producing α,β-ethylenic aldehydes in excellent yields and with very high stereoselectivity in favour of the E isomer.
