13604-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13604-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,0 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13604-51:
(7*1)+(6*3)+(5*6)+(4*0)+(3*4)+(2*5)+(1*1)=78
78 % 10 = 8
So 13604-51-8 is a valid CAS Registry Number.

Gold and Silver Complexes with the Ligands N-[Bis(isopropoxy)-thiophosphoryl]thiobenzamide and N-[Bis(isopropoxy)thiophosphoryl]-N′-phenylthiourea

Crespo, Olga,Brusko, Vasiliy V.,Gimeno, M. Concepcion,Tornil, M. Loreto,Laguna, Antonio,Zabirov, Nail G.

, p. 423 - 430 (2007/10/03)

Gold and silver complexes with the N-[bis(isopropoxy)-thiophosphoryl]thiobenzamide (HL1) and N-[bis(isopropoxy)-thiophosphoryl]-N′-phenylthiourea (HL2) ligands are reported, The compounds [M(HL)(PPh3)]TfO, [Ag(HL)(TfO)] and [Ag(HL)(PPh3)2]TfO were obtained by the reaction of both ligands with the corresponding trifluoromethanesulfonate salts. The (acetylacetonato)gold and -silver materials [M(acac)(PPh3)] or [Au(acac)(C6F5)2] cause deprotonation of the ligands and afford [ML(PPh3)] or [AuL(C6F 5)2], whereas the reaction of [Au(TfO)(PPh3)] with HL1 in a 2:1 molar ratio in KOH/MeOH affords [Au 2(L1)(PPh3)2]TfO, The first homoleptic anionic metal compounds [AuIL2]- are also reported.

REACTIONS OF N-PHOSPHORYLATED AMIDES AND THIOAMIDES WITH ALKYL HALIDES

Zabirov, N. G.,Shamsevaleev, F. M.,Cherkasov, R. A.

, p. 876 - 881 (2007/10/02)

N-Phosphorylated thioamides and also their alkali-metal salts are easily alkylated by alkyl halides at the sulfur atom of the thiocarbonyl group, and in this process the reactivities of the alkyl halides decrease in the sequence: primary>secondary>tertiary. N-Phosphorylated amides do not react with alkyl halides, whereas their alkali-metal salts form easily hydrolyzable products of alkylation at the sulfur or oxygen atom of the P=X group of the monophosphazene structure. Alkylation reactions of N-phosphorylated amides and thioamides take only one course: The formation of products of alkylation at the nitrogen atom is not observed.
