There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the α-hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts α-halo-esters and aldehydes to β-hydroxy-esters, the Simmons–Smith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:

What does organozinc chemisty describe?
Answer: physical properties, synthesis and reactions.

Just as Lee explores Jem's development in coming to grips with a racist and unjust society, Scout realizes what being female means, and several female characters influence her development. Scout's primary identification with her father and older brother allows her to describe the variety and depth of female characters in the novel both as one of them and as an outsider. Scout's primary female models are Calpurnia and her neighbor Miss Maudie, both of whom are strong willed, independent, and protective. Mayella Ewell also has an influence; Scout watches her destroy an innocent man in order to hide her desire for him. The female characters who comment the most on Scout's lack of willingness to adhere to a more feminine role are also those who promote the most racist and classist points of view. For example, Mrs. Dubose chastises Scout for not wearing a dress and camisole, and indicates she is ruining the family name by not doing so, in addition to insulting Atticus' intentions to defend Tom Robinson. By balancing the masculine influences of Atticus and Jem with the feminine influences of Calpurnia and Miss Maudie, one scholar writes, "Lee gradually demonstrates that Scout is becoming a feminist in the South, for with the use of first-person narration, she indicates that Scout/ Jean Louise still maintains the ambivalence about being a Southern lady she possessed as a child."

Who chastis Scout for the way she dresse and accuses her of ruining her family name?
Answer: Mrs. Dubose

Though Decca would continue to keep picture budgets lean, it was favored by changing circumstances in the film business, as other studios let their contract actors go in the wake of the 1948 U.S. vs. Paramount Pictures, et al. decision. Leading actors were increasingly free to work where and when they chose, and in 1950 MCA agent Lew Wasserman made a deal with Universal for his client James Stewart that would change the rules of the business. Wasserman's deal gave Stewart a share in the profits of three pictures in lieu of a large salary. When one of those films, Winchester '73, proved to be a hit, the arrangement would become the rule for many future productions at Universal, and eventually at other studios as well.

What legal decision resulted in movie studios letting their contract actors go?
Answer:
U.S. vs. Paramount Pictures, et al.
