58924-23-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58924-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,2 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58924-23:
(7*5)+(6*8)+(5*9)+(4*2)+(3*4)+(2*2)+(1*3)=155
155 % 10 = 5
So 58924-23-5 is a valid CAS Registry Number.

Ni(COD)2/PCy3 catalyzed cross-coupling of aryl and heteroaryl neopentylglycolboronates with aryl and heteroaryl mesylates and sulfamates in THF at room temperature

Leowanawat, Pawaret,Zhang, Na,Resmerita, Ana-Maria,Rosen, Brad M.,Percec, Virgil

, p. 9946 - 9955 (2011)

Reaction conditions for the Ni(COD)2/PCy3 catalyzed cross-coupling of aryl neopentylglycolboronates with aryl mesylates were developed. By using optimized reaction conditions, Ni(COD)2/PCy 3 was shown to be a versatile catalyst for the cross-coupling of a diversity of aryl neopentylglycolboronates with aryl and heteroaryl mesylates and sulfamates containing both electron-donating and electron-withdrawing substituents in their para, ortho, and meta positions in THF at room temperature. This Ni-catalyzed cross-coupling of aryl neopentylglycolboronates is also effective for the synthesis of heterobiaryls and biaryls containing electrophilic functionalities sensitive to organolithium and organomagnesium derivatives. In combination with the recently developed Nicatalyzed neopentylglycolborylation, all Ni-catalyzed routes to functional biaryls and heterobiaryls are now easily accessible (Figure presented).
