The municipal corporations that consolidated urban with country in 1995, are planning a new building or extention work of cityhall for insufitcient office space or office to he separated. But they' find it hard to calculate scale of city office space because standards of office area the Department of the Interior proposed are don't reflect now changes New changes are made a general classification two parts First in the changes of administrative plans, MC is to adapt at cityhall design plan and the number of user of cityhall office space is changed The second is social changes of An information engineering of a high order, an office automation and need for amenity of worth surrounding. Because this study proposes new standards of city office and number of user, calculate scale to be fit for consolidated cities in Gyeong-nam, make a comparision between scale of this study and practical plan
Reduction of Tertiary Amides with Borane in the Presence of Trimethyl Borate
오인환,윤녕민,경영수,Oh In Hwan,Yoon Nung Min,Gyoung Young Soo Korean Chemical Society 1989 Bulletin of the Korean Chemical Society Vol.10 No.1
Various tertiary amides have been subjected to the reduction by borane-THF in the presence of trimethyl borate at $0^{\circ}C$ and the product ratio of alcohol and amine have been analyzed in order to find out the possible way to obtain one product exclusively on the basis of the structure of amides. In the case of N,N-dimethyl derivatives of both linear aliphatic and aromatic amides the corresponding alcohols were produced predominantly. However, the bulkier tertiary amides such as N,N-diethyl and hindered acid derivatives afforded amines rather than alcohols. The mechanism of borane reduction of tertiary amides is also discussed.
