Undirected, homogeneous C–H bond functionalization: challenges and opportunities
JF Hartwig, MA Larsen - ACS central science, 2016 - ACS Publications
The functionalization of C–H bonds has created new approaches to preparing organic
molecules by enabling new strategic “disconnections” during the planning of a synthetic route. …

Denudation rates determined from the accumulation of in situ-produced 10Be in the Luquillo Experimental Forest, Puerto Rico
We present a simple method for estimation of long-term mean denudation rates using in situ-produced
cosmogenic 10 Be in fluvial sediments. Procedures are discussed to account for …

A rainfall intensity-duration threshold for landslides in a humid-tropical environment, Puerto Rico
Landslides are triggered by factors such as heavy rainfall, seismic activity, and construction
on hillslopes. The leading cause of landslides in Puerto Rico is intense and/or prolonged …

Iridium-catalyzed C–H borylation of heteroarenes: scope, regioselectivity, application to late-stage functionalization, and mechanism
MA Larsen, JF Hartwig - Journal of the American Chemical …, 2014 - ACS Publications
A study on the iridium-catalyzed C–H borylation of heteroarenes is reported. Several
heteroarenes containing multiple heteroatoms were found to be amenable to C–H borylation …

The frequency and distribution of recent landslides in three montane tropical regions of Puerto Rico
MC Larsen, AJ Torres-Sánchez - Geomorphology, 1998 - Elsevier
Landslides are common in steep mountainous areas of Puerto Rico where mean annual
rainfall and the frequency of intense storms are high. Each year, landslides cause extensive …
