Check Digit Verification of cas no

The CAS Registry Mumber 103680-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103680-47:
(8*1)+(7*0)+(6*3)+(5*6)+(4*8)+(3*0)+(2*4)+(1*7)=103
103 % 10 = 3
So 103680-47-3 is a valid CAS Registry Number.

Triethylborane-initiated room temperature radical addition of hypophosphites to olefins: Synthesis of monosubstituted phosphinic acids and esters

Deprele,Montchamp

, p. 6745 - 6755 (2001)

A novel and practical approach to monosubstituted phosphinic acid (alkylphosphonous acid) derivatives from hypophosphite salts or esters is described. Phosphorus-centered radical formation is initiated with Et3B/O2, and the reaction is conveniently conducted at room temperature in an open flask. In contrast to previously reported conditions for the radical reaction of hypophosphorous acid and sodium hypophosphite (peroxide initiators, acid catalysis, heat), the method proceeds under neutral conditions and therefore tolerates a wide range of functional groups. Previously inaccessible phosphinic acids can be prepared in a single step from cheap starting materials. Excellent selectivity is observed for monoaddition, and symmetrical dialkyl phosphinates do not form in significant amounts. Monosubstituted phosphinic acids are usually obtained in better than 90% purity by a simple extractive workup; however, isolated yields are diminished if the substituent is polar. Because radicals derived from hypophosphites are electrophilic, the reaction is limited to the use of electron-rich olefins. The reaction conditions can also be employed in the room temperature radical reduction of alkyl halides and provide an exceptionally mild and environmentally friendly alternative to the use of tributyltin hydride. The remarkable mild nature of the reaction conditions allows for the radical reaction of sensitive alkyl hypophosphites to occur, in which case, a catalytic amount of Et3B suffices to deliver alkyl phosphinate esters in reasonable yield.

Three-steps, one-pot synthesis of 2-amino-4-(hydroxyphosphinyl)butyric acid from dibutyl ester of vinylphosphinic acid was carried out with an overall yield of 66%. 3-Aminopropylphosphinic acid was prepared from allylamine in three steps with an overall y

Recent advances in phosphorus-carbon bond formation: Synthesis of H-phosphinic acid derivatives from hypophosphorous compounds

Montchamp, Jean-Luc

, p. 2388 - 2406 (2007/10/03)

This account summarizes the research conducted in our laboratory over the past five years. New methodologies were devised for the formation of P-C bonds with a focus on the reactions of hypophosphorous acid derivatives. Three types of reactions have been developed: palladium-catalyzed cross-coupling, room-temperature radical addition, and palladium-catalyzed addition. Our results are summarized in each of these areas and include some of our most recent data. (1) Our palladium-catalyzed cross-coupling has been extended to the direct coupling of alkyl phosphinates with a variety of aryl, heteroaryl, and even alkenyl electrophiles. (2) The addition of sodium hypophosphite under radical conditions is extended from alkenes to alkynes. (3) The catalytic addition of hypophosphorous compounds using palladium catalysts (hydrophosphinylation) is also discussed.
