Synthesis and crystal structures of ,2,4,6-tetra-methyl-anilinium tri-fluoro-methane-sulfonate and -iso-propyl-idene-,2,4,6-tetra-methyl-anilinium tri-fluoro-methane-sulfonate.

Two 2,4,6-tri-methyl-aniline-based trifuloro-methane-sulfonate (tri-fluoro-methane-sulfonate) salts were synthesized and characterized by single-crystal X-ray diffraction. ,2,4,6-Tetra-methyl-anilinium tri-fluoro-methane-sulfonate, [CHNH ][CFOS] (), was synthesized methyl-ation of 2,4,6-tri-methyl-aniline. -Iso-propyl-idene-,2,4,6-tetra-methyl-anilinium tri-fluoro-meth-ane-sulfonate, [CHN][CFOS] (), was synthesized in a two-step reaction where the imine, -iso-propyl-idene-2,4,6-tri-methyl-aniline, was first prepared a dehydration reaction to form the Schiff base, followed by methyl-ation using methyl tri-fluoro-methane-sulfonate to form the iminium ion.

Child guidance in interwar Scotland: international influences and domestic concerns.

Child guidance was central to twentieth-century international programs of "mental hygiene," with the shift from an emphasis on children's physical health to concern with their mental health. In interwar Britain it was supported by American philanthropy and influenced by American practice, especially the latter's emphasis on the dominant role of psychiatry. In Scotland the psychiatric model undoubtedly gained purchase.

Prenatal diagnosis of tetralogy of Fallot with obstructed supracardiac totally anomalous pulmonary venous connection.

We describe our experience with prenatal diagnosis of tetralogy of Fallot with supracardiac totally anomalous pulmonary venous connection. We also suspected obstruction in the ascending vertical vein as it crossed the right bronchus and coursed superiorly to join the right superior caval vein. This finding was confirmed on postnatal echocardiography, and at autopsy.
