An Overview of Forty Years Organotin Chemistry Developed at the Free Universities of Brussels ULB and VUB

چکیده
Esta revisão cobre os principais eixos de pesquisa desenvolvidos nas Universidades Livres de Bruxelas entre 1961 e 2001. Primeiro, introduzimos os conceitos desenvolvidos no campo das reações de quebra das ligações carbono-estanho em compostos RR’R”R”’Sn usando reagentes E-N, obtendo-se R-E e R’R”R”’SnN, em solventes nucleofilos e não nucleofilos. A adição do nucleofilo ao íon metálico é necessária para permitir a quebra da ligação metal-carbono pelo eletrofilo. A reação pode ser caracterizada pela retenção da configuração do carbono quando um retentor cíclico é usado, ou pela inversão de configuração quando este retentor não é efetivo. A estéreo-seletividade de substituições nucleofilas bimoleculares em estanho é também discutida, bem como a (in)estabilidade de várias classes de tri-organo-estanho derivados. Finalmente, a atividade in vitro anti-tumoral promissora dos compostos die tri-organo-estanhos solúveis em água é referenciada.

متن کاملI-44: Concurrent Whole-Genome Haplotyping and Copy-Number Profiling of Single Cells
Background Methods for haplotyping and DNA copynumber typing of single cells are paramount for studying genomic heterogeneity and enabling genetic diagnosis. Before analyzing the DNA of a single cell by microarray or next-generation sequencing, a whole-genome amplification (WGA) process is required, but it substantially distorts the frequency and composition of the cell’s alleles. As a conseque...
متن کاملOrganotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
