50654-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50654-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50654-42:
(7*5)+(6*0)+(5*6)+(4*5)+(3*4)+(2*4)+(1*2)=107
107 % 10 = 7
So 50654-42-7 is a valid CAS Registry Number.

Nucleophilic addition of α-(dimethylsilyl)nitriles to aldehydes and ketones

Jinzaki, Takaaki,Arakawa, Mitsuru,Kinoshita, Hidenori,Ichikawa, Junji,Miura, Katsukiyo

supporting information, p. 3750 - 3753 (2013/08/23)

α-Alkylated (dimethylsilyl)acetonitriles (Me2HSiCR 3R4CN) react spontaneously with aldehydes in DMSO to give β-hydroxynitriles in good to high yields. The addition to ketones is effectively promoted by using MgCl2/su

One-pot nitrile aldolization/hydration operation giving β-hydroxy carboxamides

Goto, Akihiro,Naka, Hiroshi,Noyori, Ryoji,Saito, Susumu

supporting information; experimental part, p. 1740 - 1743 (2011/12/16)

Rhodium to the rescue: The formal aldol products of carboxamides (CONH 2) were obtained by using a RhI(OR) (R=H, Me) catalyst under essentially neutral pH and ambient conditions. This novel aldol strategy is based on the catalytic al

Key role of Ti(IV) in the selective radical - radical cross-coupling mediated by the ingold-Fischer effect

Spaccini, Raffaele,Pastori, Nadia,Clerici, Angelo,Punta, Carlo,Porta, Ombretta

supporting information; experimental part, p. 18018 - 18024 (2009/06/28)

We report an innovative approach for the selective synthesis of polyfunctional derivatives by cross-combination of different radicals generated under mild conditions. The coordinating effect of Ti(IV) plays a key role in the reaction mechanism: due to its chelating action on the hydroxyl groups, it promotes the homolytic C-C bond cleavage of α,β-dihydroxy ketones by enhancing the captodative effect and the consequent stabilization of the corresponding α-hydroxy-α-carbonyl radicals. When these radicals are generated in the presence of stoichiometric amounts of TiCl4 and 2,2'-azo-bis-isobutyronitrile (AIBN) is employed as a source of α-cyanoisopropyl radicals, the selective radical-radical cross-coupling is observed, affording the corresponding β-hydroxynitriles in high yields. This innovative methodology allows application of the well-known Ingold-Fischer effect to a wider range of stabilized carbon-centered radicals, whose formation derives from the chelating action of Ti(IV).
