Abstract

CH2:CFCMe:CHR (I, R = cyano, SO2Ph) were prepd. by ring cleavage of the cyclopropanes II (R = cyano, SO2Ph), prepd. by treating methallyl chloride with FCHCl3 and substitution in I (R = Cl). I (R = Bu, Ph) and Me3CCH:CHCMe:CF(CH2)4Me were obtained by treating II (R = P+Ph3I-) with Me3CCHO and BuLi. I (R = H) formed an adduct with maleic anhydride. Bromination of I (R = H) at room temp. gave E- and Z-BrCH2CF:CMeCH2Br, CH2:CFCMeBrCH2Br, and CH2:CMeCBrFCH2Br. When I (R = H) was treated with Br-HOAc, CH2:CFCMe(OAc)CH2Br and CH2:CMeCF(OAc)CH2Br were obtained. [on SciFinder (R)]

Cleavage furrow

In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division. The same proteins responsible for muscle contraction, actin and myosin, begin the process of forming the cleavage furrow, creating an actomyosin ring. Other cytoskeletal proteins and actin binding proteins are involved in the procedure.

Cytokinesis

Cytokinesis (ˌsaɪtoʊkɪˈniːsɪs) is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis. During cytokinesis the spindle apparatus partitions and transports duplicated chromatids into the cytoplasm of the separating daughter cells. It thereby ensures that chromosome number and complement are maintained from one generation to the next and that, except in special cases, the daughter cells will be functional copies of the parent cell.

Rhenium

Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. Rhenium has the third-highest melting point and second-highest boiling point of any element at 5869 K. Rhenium resembles manganese and technetium chemically and is mainly obtained as a by-product of the extraction and refinement of molybdenum and copper ores.
