According to his Oxford University profile, Anderson's research has " a particular focus on the total synthesis of biologically active molecules, and the development of new reactions including cascade processes . . . Within the theme of reaction development, we have particular interests in the use of metal-mediated reactions to rapidly construct complex functional molecules, and in new applications of organosilicon chemistry ."

From 1954 to 1972 M�ller taught as head of the Institute of Silicone and Fluorocarbon Chemistry at the Dresden University of Technology, where the Faculty of Mathematics and Science, awarded him an honorary doctorate in 1992 in recognition of outstanding achievements in the field of organosilicon chemistry . The citation particularly acknowledged his seminal work on industrially applicable synthesis of methylchlorosilanes, research contributions to the development of silicon organic chemistry and the long years of teaching at the university.

:The Si-Si bond is readily broken in the presence of oxygen, so presumably an oxygen atmosphere is out of the question . ( If it is not, the silicon organism in an oxygen atmosphere must excrete SiO 2 ( quartz ), which is not really a problem if it does not " breathe " it out . ) And while SiO 2 is quite stable, it is the starting material for synthesis of many organosilicon compounds, so presumably life could get started even if most silicon became bound as parts of SiO 2 macromolecules.

The Convention prohibited the dumping of halocarbons and organosilicon ( with some exceptions ), mercury and mercury compounds, cadmium and cadmium compounds, non-biodegradable plastics and other persistent materials, as well as " substances which have been agreed between the Contracting Parties as likely to be carcinogenic under the conditions of disposal . " It also restricted and required a permit for the dumping of arsenic, lead, copper, zinc and their compounds, as well as cyanides, and fluorides, pesticides, containers, " tar-like substances ", scrap metal, and " other bulky wastes ."
