α-Deuteriobenzaldehyde tosylhydrazone is a chemical compound derived from benzaldehyde, where one hydrogen atom on the alpha carbon is replaced with a deuterium atom, and the molecule is further modified by the addition of a tosylhydrazone group. α-deuteriobenzaldehyde tosylhydrazone is often used in organic synthesis and chemical research, particularly in the study of reaction mechanisms and isotope effects. The tosylhydrazone group serves as a protecting group and can be used to control the reactivity of the molecule, while the deuterium atom provides a means to track the movement of atoms through chemical reactions. α-deuteriobenzaldehyde tosylhydrazone is valuable for understanding the kinetics and thermodynamics of various chemical processes, as well as for the development of new synthetic methods and the study of isotope effects in organic chemistry.

7318-30-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7318-30-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,1 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7318-30:
(6*7)+(5*3)+(4*1)+(3*8)+(2*3)+(1*0)=91
91 % 10 = 1
So 7318-30-1 is a valid CAS Registry Number.

1,2,4,6-CYCLOHEPTATETRAENE: THE KEY INTERMEDIATE IN ARYLCARBENE INTERCONVERSIONS AND RELATED C7H6 REARRANGEMENTS

McMahon, Robert J.,Abelt, Christopher J.,Chapman, Orville L.,Johnson, Jeffery W.,Kreil, Curits L.,et al.

, p. 2456 - 2469 (2007/10/02)

Thermolysis or photolysis of phenyldiazomethane (2) produces phenylmethylene (3), which ring-expands to give 1,2,4,6-cycloheptatetraene (6).Spectroscopic and chemical evidence rule out bicyclo(4.1.0)hepta-2,4,6-triene (4), cycloheptatrienylidene (5), and bicyclo(3.2.0)hepta-1,3,6-triene (11) intermediates.The strained allene in cycloheptatetraene (6) exhibits infrared absorption at 1824 and 1816 cm-1.Deuterium substitution produces the expected 10-cm-1 shift in the allene absorption.Fluorine or chlorine substitution substantially enhances the allene absorption intensity.Deuterium labeling studies reveal that the intramolecular chemistry of cycloheptatetraene (6) involves reversible thermal or photochemical equilibriation with phenylmethylene (3).The intermolecular chemistry of 6 involves dimerization.At temperatures as low as 10 K, 6 forms a labile (2+2) dimer,7, which undergoes thermally allowed, electrocyclic ring opening to give heptafulvalene (8) upon warming to room temperature.The rearrangements of 7-acetoxynorbornadiene (9), 2-diazobicyclo(3.2.0)hepta-3,6-diene (31), and 8-diazobicyclo(2.2.2)octa-2,5-dien-7-one (33) all involve cycloheptatetraene (6) intermediates.
