A Simple Method for the Alkylation of Diethyl Malonate

Alkylmalonic esters, which have been recognized as important intermediates in the syntheses of various carboxylic acids, amino acids, etc., can be obtained by a variety of methods.1) Excepting the introduction of tertiary alkyl groups, the alkylation of malonic esters with alkyl halides in basic conditions, for example, in ethanol in the presence of sodium ethoxide, is one of the most important...

Diethyl 5-acetamido-3-methyl­thio­phene-2,4-dicarboxyl­ate

The title compound, C(13)H(17)NO(5)S, is approximately planar (r.m.s. deviation for the non-H atoms = 0.055 Å). Its conformation is stabilized by N-H⋯O and C-H⋯O hydrogen bonds, which both generate S(6) rings. The crystal packing only features van der Waals contacts.

2-Benzoyl-1,1-diethyl-3-phenyl­guanidine

In the title tetrasubstituted guanidine, C(18)H(21)N(3)O, the guanidine and carbonyl groups are not coplanar, as reflected by the torsion angles involving the N=C atoms [17.6 (3), -141.68 (17) and 42.2 (3)°]. This is probably due to the absence of an intra-molecular N-H⋯O hydrogen bond, forming a six-membered ring, and is commonly observed in this class of compounds. In the crystal structure, c...

1,1-Diethyl-3-(4-meth­oxy­benzo­yl)thio­urea

In the title compound, C(13)H(18)N(2)O(2)S, the 4-meth-oxy-benzoyl fragment is approximately planar [maximum deviation = 0.057 (2) Å] and twisted relative to the thio-amide fragment, forming a dihedral angle of 86.62 (6)°. The two Csp(2)-Nsp(2) bonds in the thio-urea unit differ significantly in length [1.327 (2) and 1.431 (2) Å]. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into ch...

Synthesis of Quaternary Salts from 2 , 3 ' - B ip y r id in e and Dibromoalkanes

There has been considerable interest in the pro­ ducts of the reaction of 2 ,2 '-bipyridine with di­ bromoalkanes. The bridged diquaternary salt (1) from 2 ,2 '-bipyridine and 1 ,2 -dibromoethane is the well-known herbicide diquat dibromide [1]. Similar bridged salts are obtained with 1,3-dibromopropane and 1,4-dibromobutane [2] but reaction of 2,2'-bipyridine with 1,5-dibromopentane gives inst...
