    Notes: Abstract Hermitean vector spaces E of infinite dimensions are considered. Let G be a subgroup of the orthogonal group of E acting on a set M. The ‘Lattice Method’ is a technique for classifying the orbits in M under G. We discuss the method in abstract terms and we illustrate it by means of three classification results showing that it is decisive to do a considerable amount of explicit calculations with vector subspace lattices.

    Description / Table of Contents: Derivatives of o-Phenylene Phosphate. 34. Halogenation of o-Methoxyphenyl Phosphinites, Phosphonites, and Phosphiteso-Methoxyphenyl phosphinites, phosphonites, and phosphites react with halogenes to halogenophosphonium-halides 4, which are stabilized by ligand exchange with the starting material to phosphonium salts or by elimination of methylhalide to cyclic phosphoranes.
    Notes: o-Methoxyphenyl-phosphinite, -phosphonite und -phosphite reagieren mit Halogenen zu Halogenphosphoniumhalogeniden 4, die sich entweder durch Ligandenaustausch mit dem Startprodukt als Phosphoniumsalze oder durch Abspaltung von Methylhalogenid als cyclische Phosphorane stabilisieren.

    Description / Table of Contents: Derivatives of o-Phenylene Phosphates. XVIII. Bromination of o-substituted Aromatic o-Phenylene PhosphitesAryl-o-phenylene phosphites of the type 4 at room temperatures give with bromine by cyclization of the primary adduct the bromo-spirophosphorane 6A as the main product. As by products phosphorus tribromide, pentaoxyphosphoranes 10, and o-substituted phenyl-dibromophosphites 8 could be identified. The formation of the observed products can be explained by assumption of ligand-exchange reactions.
    Notes: Aryl-o-phenylenphosphite des Typs 4 geben bei Raumtemperatur mit Brom unter Cyclisierung des Primärproduktes als Hauptprodukt das Brom-spirophosphoran 6A; als Nebenprodukte wurden Phosphortribromid, Pentaoxyphosphorane 10 und o-subst. Phosphorigsäurephenylesterdibromide 8 nachgewiesen. Die Bildung der Produkte kann durch Ligandenübertragungsreaktionen erklärt werden.
